What is the problem with my code ?
When I run it, at first time it works normally and displayed the output as expected
but at the second time it displayed the following error
I tryed to re-open the MATLAB ..
but if I try the code twice it display the error , but if only once everything displayed as expected
Error in proj (line 147)
p3(k2,:)=xcur';
CODE
%Initial condition
xcur=(B*cur)+c;
p3(k2,:)=xcur';
fprintf(fid,'%3.6f\t%0.6f\t%0.6f\t',xcur);
curnorm=xcur-cur;
%Finding the norm
max3=0;
for i=1:4;
if abs(curnorm(i,1))>max3;
max3=abs(curnorm(i,1));
end
end
p4(k2,1)= max3; %For plotting
fprintf(fid,'%3.6f\n',max3);
if max3 >T;
condition3=1;
else
condition3=0;
end
cur=xcur;
end
for i=1:4
p3(i,4+1)=p4(i,1);
end

In your last for-loop is it really
for i=1:4
p3(i,4+1)=p4(i,1);
end
that you want to write? The second index to p3 is actually 5 so maybe this causes the error?

xcur=(B*cur)+c;
p3(k2,:)=xcur';
xcur.' must be a column vector of the same length as that the first time on each subsequent pass. There's insufficient data presented to tell just what any dimensions are.
Use
dbstop on error
and see what the sizes of the terms are. That will, in all likelihood, reveal the logic error.
