z=[];
for i=1:length(x)
    g=h.*x(i);
    z=[z;g];
end
[r c]=size(z);
k=r+c;
t=2;
y=[];
cd=0;
while(t<=k)
    for i=1:r
        for j=1:c
            if((i+j)==t)
                cd=cd+z(i,j);
            end
        end
    end
    t=t+1;
    y=[y cd];
    cd=0;
end

what variables should i put into my parameters I tried something like below

function Y=my_conv(x,h)

-----

end

didnt work out as expected

Please mention, what "didn't work as expected" means. Of course this would be the way to go. If you have any troubles with this, explain us, which problem you have. It is much easier to solve a problem than to guess, what the problem is.

The only problem I see is the uppercase Y, while you use the lowercase y in the code.

A simplified version of your code:

function y = my_conv(x, h)
z = x(:) .* h;
[r, c] = size(z);
y  = [];
for t = 2:r+c
    cd = 0;
    for i = 1:r
        for j = 1:c
            if i+j == t
                cd = cd + z(i,j);
            end
        end
    end
    y = [y, cd];
end
end
