## How do you sort a matrix in a row major order?

Sort the matrix row-wise and column-wise

1. Sort each row of the matrix.
2. Get transpose of the matrix.
3. Again sort each row of the matrix.
4. Again get transpose of the matrix.

## Can you rearrange matrix rows?

Switching Rows

You can switch the rows of a matrix to get a new matrix. In the example shown above, we move Row 1 to Row 2 , Row 2 to Row 3 , and Row 3 to Row 1 . (The reason for doing this is to get a 1 in the top left corner.)

## How do you sort a matrix?

Approach: Create a temp[] array of size n^2. Starting with the first row one by one copy the elements of the given matrix into temp[]. Sort temp[]. Now one by one copy the elements of temp[] back to the given matrix.

## How do you change a row in a matrix?

How to Perform Elementary Row Operations

1. Interchange two rows. Suppose we want to interchange the second and third rows of A, a 3 x 2 matrix. …
2. Multiply a row by a number. Suppose we want to multiply each element in the second row of Matrix A by 7. …
3. Multiply a row and add it to another row. Assume A is a 2 x 2 matrix.

In other words, in matrix multiplication, the order in which two matrices are multiplied matters!

## Can you reorder the columns of a matrix?

Click the Column Tools tab, then select Sort By Column. Note you should still have the Duration column selected, so choose PCSort2 from this list. Wait for Power BI to update, then your matrix should automatically reorder the columns for you.

## How would you store the following matrix in memory if row-major order is used?

If row-major order is used, how is the following matrix stored in memory? Explanation: It starts with the first element and continues in the same row until the end of row is reached and then proceeds with the next row. C follows row-major order. 7.
