%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?

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

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
