Sparse matrix into square by adding zeros

Hi!

I am working with a sparse matrix that is size 6893x6881 but I would like it to be square i.e. 6893x6893. Does anyone have a suggestion on how to add zeros so that my matrix is square?

Hi Axelina,

I understand from your query that you want to convert your 6893x6881 sparse matrix to a 6893x6893 square matrix.

Assuming that your matrix is name 'm', this can be done by the following line of code:

m(:,6893) = 0;

This populates the columns till 6893 with value 0.

Hope this helps!
