In other words, how can I call the function like:. What am I doing wrong here? Don't worry about the aa and bb variables. Any decent compiler will optimize them away. First of all, your code has a memory leak. You overwrite the previous value of C without ever freeing it. To transpose in place, you need to just swap all the right indexes without swapping twice. So it's like the same problem as reversing an array in place. Learn more.

KOB It does not. Notice we loop for i from 0 to n and for j from 0 to i exclusive? This means you'll never swap twice because j will always be less than i, so you will never loop over both elements i, j and j, iundoing a swap.

Sorry, I thought both i and j were looping 0 through n. I was trying to get something along the lines of this working. And how do I then declare C and pass it into the function? Don't forget to free the old C, else you will get a memory leak.

And, Memory leak?Here we will use the function.

Matrix Operations in C | Addition, Multiplication, Transpose

For this purpose, we should know how to the multidimensional array passed to a function. Matrix addition is the operation of adding two matrices by adding the corresponding entries together. The matrix can be added only when the number of rows and columns of the first matrix is equal to the number of rows and columns of the second matrix. Enter b[0][0] Enter b[0][1] Enter b[0][2] Enter b[1][0] Enter b[1][1] Enter b[1][2] Enter b[2][0] Enter b[2][1]:9 Enter b[2][2] Entered first matrix is: 12 13 25 32 14 20 32 25 18 Entered second matrix is: 29 26 27 35 42 50 12 9 We can multiply two matrices if, and only if, the number of columns in the first matrix equals the number of rows in the second matrix.

Otherwise, the product of two matrices is undefined. Enter b[0][0]:5 Enter b[0][1]:6 Enter b[0][2]:2 Enter b[1][0]:3 Enter b[1][1]:8 Enter b[1][2]:7 Enter b[2][0]:9 Enter b[2][1]:4 Enter b[2][2]:1 Entered first matrix is: 1 2 3 4 5 6 9 8 7 Entered second matrix is: 5 6 2 3 8 7 9 4 1. Transpose of matrix A is represented by A T. Skip to content Here we will use the function. C program to find Addition of two Matrix Matrix addition is the operation of adding two matrices by adding the corresponding entries together.

How to find transpose of a given matrix in C. Logic to find transpose of a matrix in C programming. Basic C programmingFor loopArray. Transpose of a matrix A is defined as converting all rows into columns and columns into rows. Transpose of matrix A is written as A T. Example Input Input elements in matrix: 1 2 3 4 5 6 7 8 9 Output Transpose: 1 4 7 2 5 8 3 6 9. Enter elements in matrix of size 3x3: 1 2 3 4 5 6 7 8 9 Original matrix: 1 2 3 4 5 6 7 8 9 Transpose of matrix A: 1 4 7 2 5 8 3 6 9.

I will help my best. Before commenting you must escape your source code before commenting.It is important that we should know How A For Loop Works before getting further with this transpose program.

It is also known as a Three — Dimensional Matrix. The Transpose of any Matrix can be found out by different methods. The Third method makes use of Functional approach in C Programming. This is just awesome. I was finding transpose using only one array variable and I got so many variants. Transpose Program is so simple.

I had thought it was very difficult. I could not make the for loop. Tried so many variants. This code is good. I finally understood how to pass array to a function with the help of this C program to find transpose of a matrix.

I'm writing a program to transpose a given matrix using allocated memory. Please help. The problem is that matrix is indexed by i then j, not j then i like you are doing in the second and third line in the while loop. Then you can output like below, or delete matrix and reassign matrix to be result as you wish. My entire transpose function became the following code row and col need not be pointers to int pass by value is just fine.

Also accessing matrices should use array subscripts as it is nicer style :. If count of columns is greater then count of rows, allocated for matrixyou'll read and write non-allocated memory. IMHO, It would be better to store whole matrix in continuous memory.

Not in different pieces. In this manner the code would look like this:. At the end, I think, that it would be the best way to look at std::vector. If you want, I can show you, how will you function look with vector. Learn more. Asked 7 years, 1 month ago. Active 4 years, 5 months ago.

C Program to Find Transpose of a Matrix

You can do this by copying, pasting, and using the Transpose option. But doing that creates duplicated data. Excel inserts curly brackets at the beginning and end of the formula for you.

For more information on array formulas, see Guidelines and examples of array formulas. First select some blank cells. But make sure to select the same number of cells as the original set of cells, but in the other direction. For example, there are 8 cells here that are arranged vertically:. So, we need to select eight horizontal cells, like this:. This is where the new, transposed cells will end up.

Excel will look similar to this:. Notice that the eight cells are still selected even though we have started typing a formula. Now type the range of the cells you want to transpose.

In this example, we want to transpose cells from A1 to B4. Just stop typing, and go to the next step. An array formula, in short, is a formula that gets applied to more than one cell. Because you selected more than one cell in step 1 you did, didn't you?

You don't have to type the range by hand. Just click and drag from the beginning of the range to the end. Need text and cell formatting to be transposed as well? Try copying, pasting, and using the Transpose option. But keep in mind that this creates duplicates. So if your original cells change, the copies will not get updated.

There's more to learn about array formulas. Create an array formula or, you can read about detailed guidelines and examples of them here. The TRANSPOSE function must be entered as an array formula in a range that has the same number of rows and columns, respectively, as the source range has columns and rows. An array or range of cells on a worksheet that you want to transpose.

The transpose of an array is created by using the first row of the array as the first column of the new array, the second row of the array as the second column of the new array, and so on. If you're not sure of how to enter an array formula, see Create an array formula. Transpose rotate data from rows to columns or vice versa.
