How can I create matrix with the size N,m?
How can I copy each array of matrix in a vector and make the modification in it
and the replace again in the matrix?
Example
vector = M (1,:)
after modification of the vector
M(1,:) = vector
But an error appear " Index exceeds matrix dimensions."

the size of matrix M is N = 10 and m = 4
M = 1 2 0 3
0 0 3 5
6 4 2 0
.
.
N
vector = M(1,:)
vector = 1 2 0 3
appear the error

vector = M (1,:)
% Somewhere between these two lines your vector is changing in one
% of the following 2 ways:
% 1) it's length is changing
% 2) it is converted to a column vector instead of a row vector
% 3) an additional row is added to the vector making it a matrix
M(1,:) = vector

Hi, May be after modification you vector became a column vector. Try
M(1,:) = vector';
If this doesn't work, provide the value of size(vector).
Hope this helps!
