Same loop have different vector output

1 view (last 30 days)
Sir, when i am running this loop for f_s the first f_s1 is comming as a column vector while f_s2, 3, 4, 5, are comming as a row vector.
Please sir, suggest me where i amking the mistakes.
utdelt=([1;2;3;4;5;6;7;8;9;10;11;12;13;14;15]);
Ktts=rand(6,6);
for i=1:1:10
for n=1:1:5
if n==1
Utdelt=([zeros(3,1); (utdelt(1:3,i))]);
eval(['Utdelt',num2str(n),'=[zeros(3,1); (utdelt(1:3,i))]']);
else
Utdelt=utdelt([((1+(n-2)*3):(6+(n-2)*3)),i]);
eval(['Utdelt',num2str(n),'=[utdelt((1+(n-2)*3):(6+(n-2)*3,i)]']);
end
eval(['Ktts',num2str(n),'l']);
eval(['f_s',num2str(n),'=Ktts*Utdelt']);
end
end

@Walter Roberson sir, detailed problem it is there.
sir, problem is coming in this line, because f_s2, 3, 4,5 is coming as a row vector and the Utdelt value also not taking properly. So suggest me about this line.
eval(['f_s',num2str(n),'=Ktts*Utdelt']);

"Please sir, suggest me where i amking the mistakes."
The obvious mistake is that you are forcing meta-data into variable names.
That forces you into writing slow, complex, inefficient, obfuscated, buggy code that is hard to debug (which is exactly what your question demonstrates, and hopefully you are about to start to notice).

When you do not post actual code, then we cannot give you actual answers.
For the code that you posted the bug is that Ktts1l is not defined.

@Walter Roberson sir, just tell me is it correct? if wrong please correct me.
utdelt=([1;2;3;4;5;6;7;8;9;10;11;12;13;14;15]);
nodof=3;
for i=1
for n=1:1:5
if n==1
Utdelt=([zeros(nodof,1); (utdelt(1:nodof,i))]);
eval(['Utdelt',num2str(n),'=[zeros(nodof,1); (utdelt(1:nodof,i))]']);
else
Utdelt=utdelt([(1+(n-2)*nodof):(6+(n-2)*nodof),(i)]);
eval(['Utdelt',num2str(n),'=[utdelt([(1+(n-2)*nodof):(6+(n-2)*nodof,(i)])]']);
end
end
