r=[0.5,1,1.5....5]; theta= linspace(0,2*pi,73); [theta,r]=meshgrid(theta,r); [x11,y11]=pol2cart(theta,r); x1= x11(:);
% I have a function z whose input needs to be x and y between [-1,1] so I need to change x and y both %such that for x1>1, x=1, x1<-1, x=-1 and -1<=x1<=1, x=x1 % i tried this for k=1:length(x1) if x1(k)<-1 x(k)=-1 else if x1(k)>=-1 && x1(k)<= 1 x(k)=x1 else if x1(k)>1 x(k)=1 end end
z= 1.3249-.004937*x+5.43243*x.^2-1.153*x.*3+4.2693*y.^6 % Repeating same for Y as well. when I run this i get In an assignment A(I)=B and I must be same. Is anyone able to help me. Thanks in advance

for k=1:length(x1)
if x1(k)<-1
x(k)=-1
elseif x1(k)>=-1 && x1(k)<= 1
x(k)=x1(k)
else x1(k)>1
x(k)=1
end
end
Sorry, didn't realize I didn't have the "code" option selected, should be easier to read now. The problem you are getting is because you are currently trying to make x(k)=x1, but x1 is currently a vector, and you only need the corresponding element x1(k).
Hope this helps.

any chance that you could post the code you used? it would make it easier to follow what you are asking
