any kind folks who can help me out. i'm trying to implement least square method, but i'm getting some error using linsolve and '\' function. please help, and million thanks in advance!
for a =1:400
for P=1:49
o=(P-1)*243;
for r=1:35
if r==35
t=-2;
pA1(1:5,1,r,P)=A(7*r-6+o:7*r+t+o,a);
pB1(1:5,1,r,P)=B(7*r-6+o:7*r+t+o,a);
beta(r,P)=linsolve(pA1,pB1); <--- error
% beta(r,P)=pA1\pB1;
else
t=0;
pA(1:7+t,1,r,P)=A(7*r-6+o:7*r+t+o,a);
pB(1:7+t,1,r,P)=B(7*r-6+o:7*r+t+o,a);
beta(r,P)=linsolve(pA,pB);; <---- error
% beta(r,P)=pA\pB;
end
end
end

Can you please tell us what the complete error message is. We cannot read minds, and we also cannot read what is on your computer screen.
