Hello all.
I have one vector as a function of x of length 1220 point and another vector as a function of y of length 1933 point. These points are arbitrary measure of my x and y distance respectively. I want to multiply them together to get a third vector of x and y, then I want to plot with x and y. Any help how can I do it will be appreciated.

Note that my x and y distance are different from each other.

‘Note that my x and y distance are different from each other.’
The interp1 function is your friend here.

let me describe the problem in better way. I have two field, one in x direction described over length w, and the other in y described over range h. I have two plots of them which I am attaching. What I want to do is multiply them together over the rectangle of area w*h. My question is how to multiply them?

I can’t suggest anything other than what I already posted. It seems to me that you are doing matrix multiplication, so that something like this is what you want:
m = w(:) * h(:)';
This will produce matrix ‘m’ that has ‘length(w)’ rows and ‘length(h)’ columns.
