multiply 200x1 matrix with 200x200 mqtrix in matlab

To multiply a 200x1 matrix with a 200x200 matrix in MATLAB, you need to use the matrix multiplication operator *.

Here's an example code that demonstrates how to do this:

main.m
% Create a 200x1 matrix
matrix1 = rand(200,1);

% Create a 200x200 matrix
matrix2 = rand(200,200);

% Multiply the two matrices
result = matrix2 * matrix1;

9 lines

The resulting matrix result will be a 200x1 matrix.

Please note that in MATLAB, for matrix multiplication, the number of columns in the first matrix should match the number of rows in the second matrix.
