I have a bit of code which generates a value P and updates it every iteration. How can i store each of these values generated and then plot them on a graph?

for k=1:100
p(k)=%your update for p
end

I keep getting the error 'Unable to perform assignment because the left and right sides have a different number of elements.'
P=zeros(1000,1);
for n = 1:1000
P(n) = nonzeros(Q_new.*C);
end
Any ideas why this might be? Q and C are both 10x100 matricies which also update every iteration

Use a cell array. Your sizes each iteration might be different based on the number of nonzeros.
P=cell(1000,1);
for n = 1:1000
P{n} = nonzeros(Q_new.*C);
end
