I am trying to let the user enter input in matrix form

matr = input ('enter values in matrix form [a,b; c,d]');

but how can I make sure that the user input 2 columns only but whatver rows. I am new to manipulating array and matrix.

if size(matr,2)>2
 disp('Has more than 2 Columns beware!')
end

thank you. Can you explain what are the arguments for the size?

matr represents the input matrix data and 2 represents the number of columns , reading the documentation of size() will clear things for you.

doc size % in command window
help size
