How would I delete rows in a tall matrix to make it into a square matrix? When given a tall matrix, what can I run to turn that tall matrix into a square matrix?

If i am right then....

Tall matrix, if m>n here m= row, n= column

Wide matrix, if m<n

Square matrix, if m=n

So, i think you have to add column to convert into square matrix from tall matrix, not deleting row.

m=4; % row
n=3; % column
tall_matrix=randi(10,m,n);
add_col= randi(10,n+1,1);
square_matrix= [tall_matrix add_col]

square_matrix = 4×4
