Replace "eval" in vectors created inside a loop

1 次查看(过去 30 天)
I created a GUI that requests info from the user, which is then saved into series of variables (e.g. Fp1, Sn1, Fp2, Sn2, Fp3, Sn3...) and into different files (Info1.mat, Info2.mat, Info3.mat...). Once I have collected all of them, there's a vector created inside a loop with the value of each one of them. For example:
Fp1=0.8;
Fp2=0.9;
Fp3=0.85;
and I want to get:
Fp=[0.8 0.9 0.85];
I have already tried the following code:
for jj=1:1:ng
Fp(jj)=eval(sprintf('Fp%d',jj),ii);
end
which is working fine, but I would like to know if there're other suggestions to do the same without "eval". Thank you in advance.

In your GUI, I would simply save them to ‘Fp(1)’ instead of ‘Fp1’ when they’re entered, and so for the others. Providing that they’re scalars (and they are in your example), that should work.

Oh I see, the thing is that the values can't be requested by dialog boxes, but they're entered in different edit boxes (Fp is the one in the red circle) from a GUI; so when all the information has been written and the user pushes "Siguiente" (Next), everything saves into a .mat file which will make some calculations later.

I have no idea how your code is importing them from your GUI. If it is importing them as a vector or cell array, you can address individual elements of the vector or cell array.
In any event, if you are now importing them as ‘Fp1’ now, you can likely change your code to import them instead as ‘Fp(1)’, and so for the others.
