How can I multiply two different sized objects?

%Matrix dimensions must agree.

A = 1;
pas = 1/1000;
t=-10:pas:10;
k=10;
omega = -k*pi/A:1/10:k*pi/A; 

x=omega.*t;

%The error appears on the last line where x is. how can i multiply them?

Answer 1

[madhan ravi]

omega = linspace(-k*pi/A,k*pi/A,numel(t)); % change your line to this

Answer 2

[Totanly]

you can't multiply two different sized vectors. Follow the matrix multiplication rules.

if A=first matrix and B=second matrix

size(A) should be Size(B) for element by element multiplication;

no of columns of A= no of rows of B for matrix multiplication

and how i can adapt this theory to my problem?
