hello, i am using function block in matlab simulation .in that want to generate matrix X1 from matrix A
for j1=1:k2
for j2=1:m1
for j3=1:n1
X1(m1*(j1-1)+j2,j3)=A(j2,j3);
end
end
end
but executing code am getting error....
Undefined function or variable 'X1'. The first assignment to a local variable determines its class.
Function 'Subsystem9/Mtesting' (#53.2154.2156), line 66, column 16:
"X1"
Launch diagnostic report.

Preallocate X1 before the loop.
X1=zeros(m1*k2,n1);
