skew symmetric matrix [a] in matlab

To skew-symmetric a matrix [A] in MATLAB, you can use the following code:

main.m
A = [1, 2, 3; 4, 5, 6; 7, 8, 9]; % Example matrix

skew_symmetric_A = (A - A.') / 2;

Here's what the code does:

• A is the input matrix.
• A.' is the transpose of matrix A.
• (A - A.') subtracts the transposed matrix from the input matrix.
• / 2 is used to scale the resulting matrix.

By following these steps, you can obtain the skew-symmetric matrix [skew_symmetric_A] from the input matrix [A].
