I have a data with a matrix size of 258x1 and I need it to be how 6204x1 matrix. How do I expand the matrix to become a 6204x1 matrix?

Well how do you plan to get the other 6000ish elements? What are they?

You can use interp1

%%example

n=1:258
data=sin(0.1*n)
figure;
plot(n,data);
ni=linspace(1,258,6204);
datai=interp1(n,data,ni)
figure;
plot(ni,datai)
