I try to run this code to solve an n x n linear
system using the Gaussian Elimination Methods
but it says there is error in Error: File: mad.m Line: 7 Column: 20
Illegal use of reserved keyword "for".
can anybody solve the problem and send the code?
for i=j+1:m
a(i,:)=a(i,:)-a(j,:)*(a(i,j)/a(j,j));
enda = input('Enter the augument matrix:');
[m,n]=size(a);
for j=1:m-1
for z=2:m
if a(j,j)==for i=j+1:m
a(i,:)=a(i,:)-a(j,:)*(a(i,j)/a(j,j));
enda = input('Enter the augument matrix:');
[m,n]=size(a);
0;
t=a(j,:);a(j,:)=a(z,:);
a(z,:)=t;
end
end
end
end
end
x=zeros(1,m);
for s=m:-1:1
c=0;
for k=2:m
c=c+a(s,k)*x(k);
end
x(s)=(a(s,n)-c)/a(s,s);
end
disp('Gauss elimination method:');
a;
x';

This code came from the answer here. Don't invest too much time trying to fix random junk code you find on the internet.

To echo with what's already mentioned on this thread, "for" is a reserved keyword in MATLAB, we cannot use this as another variable. You might have to rearrange your code accordingly to avoid the error.
