overwrite matrix A with matrix B (which has another size)

Asked by Nicole on 4 Jun 2014
Latest activity Answered by Henric Rydén on 4 Jun 2014

Hi,

I would like to overwrite matrix_a with an extended matrix_b.

matrix_a has the dimension 19x57 and is full of data.

    matrix_b = [zeros(1,57) matrix_a] 
    matrix_a = matrix_b; 

matrix_a has to be updated and I use this matrix in a loop.

The Error: "Size mismatch (size [57 x 19] ~= size [57 x 20])."

Is there any way to overwrite matrix_a with another matrix with different size?

Thanks! Greeting
