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
It works correctly.
