Hi! So I try tu run my program that include A=A((x:y,:)) in it but it said Unrecognized function or variable 'a'. I thought it was for declaring zeros matrix? I really have no idea for this

x = 1
y = 2
A = [1, 2;
3, 4;
5, 6]
A(x:y, :) % read about matrix indexing
doc zeros % to create a zeros matrix

Okay, so first check that you had defined matrix 'A' in you code before trying to access it and use single paranthesis for indexing, this should be "A=A(x:y, :)".
