how do i sum the products of ane^j(theta)n from n=0,1,2… if the error says the sum block says it was expecting a real input but is driven by a complex input?

the 1st part of Walter's answer has syntax error:
- it's most likely that t will have a higher amount of elements than vector n
- therefore sin(n.*pi.*t) will always find one or more terms (of n) with a numel(n) href = ""</a> numel(t) mismatch
returning error, from the attempted d.*t
.
Let me suggest the following:
L=100; t=[0:2/L:2]; x=zeros(1,numel(t)); for n = 1:2:15 x=x+ sin(n*pi*t)/n; end; x=x+.5/pi plot(t,x);grid on
.
Increase L to improve signal time resolution.

>> A = complex(randi([-3,3],4,4),randi([-3,3],4,4)) % fake data
A = -2 + 3i -2 + 1i 2 - 3i -2 + 1i -2 + 0i 3 + 0i -3 + 3i 0 + 0i 2 + 0i 2 - 2i 3 + 3i 0 - 3i 1 - 2i -3 - 2i 3 + 2i 0 - 2i>> B = complex(real(A).*(real(A)<=0.5),imag(A)) % set real(A)>0.5 to 0.
B = -2 + 3i -2 + 1i 0 - 3i -2 + 1i -2 + 0i 0 + 0i -3 + 3i 0 + 0i 0 + 0i 0 - 2i 0 + 3i 0 - 3i 0 - 2i -3 - 2i 0 + 2i 0 - 2i
