Returning workspace outputs is supported with only single return argument
Dear,
I am trying to run a simulink model in m-code while optimizing ADRC parameters with PSO, but I get an error：
‘Returning workspace outputs is supported with only single return argument’.
The first figure is ‘PSO_ADRC’ code and the second figure is the simulink model ‘ADRC_test’.
Hope someone can help me, thanks.Dear,

How do I merge vectors?

Can you explain the difference between the two matrix operations in MATLAB?
I am trying to understand how MATLAB performs the following matrix operations:
Example 1:
clearvars; clc; close all;
Nx = 8;
Ny = 8;
Lx=2*pi;
dx = Lx/Nx;
Vec = fftshift(-Nx/2:Nx/2-1);
Vector1 = (sin( Vec * dx/2)/(dx/2)).^2 ;
[Matrix2,x] = cheb(Ny);
for m = 1:length(Vec)
Matrix1 = -1 * (Vector1(m))+ Matrix2;
end
Example 2:
clearvars; clc; close all;
Nx = 8;
Ny = 8;
Lx=2*pi;
dx = Lx/Nx;
Vec = fftshift(-Nx/2:Nx/2-1);

Igl = speye(Ny+1);
[Matrix2,x] = cheb(Ny);
for m = 1:length(Vec)
Matrix1 = -Igl * (Vector1(m))+ Matrix2;
end
Why is Matrix1 different in Example1 and Example 2? In particular, in Example 1 how is the scalar multiplication of the row vector (Vector1(m)) added to Matrix 2?

LTE Turbo encoder with R = 1/2 – BER performance with LTE Toolbox
Hi there,
I am trying to make BER performance of LTE Turbo encoding with rate matching R = 1/2. But, when I implement symbol modulation and demodulation I can’t get BER = 0 (without any AWGN existence). This indicates that problem is in mod/demod part. I will be also great to use BPSK instead of QPSK but lteSymbolModulate doesn’t have this modulation scheme. Thank You in advance.
