I have the following code:

for x = 1:0.01:1.5
    z = g(x,rpf);
end

but when I run this (assume my function is correct), I only get that z is equivalent to the last data point. How can I store x and z in a matrix and then plot them?

You need to index z with each loop.

count = 0;
for x = 1:0.01:1.5;
    count = count + 1;
    z(count) = g(x,rpf);
end
plot(x,z)

Can I ask a follow-up? How could I do an outer loop for different values of rpf and then plot each one on the same plot? And the values for rpf would be like specific values: (i.e. 5.4, 6.7, 5.2 etc) Any ideas how I would do this? When I try it, it just keeps adding move rows to z, rather than just overwriting it on the next loop
