Coder - Static size string in sprintf
显示 更早的评论
How can I prevent MATLAB Coder to generate variable size code for a simple number insertion into a string?
for i=1:4
name=sprintf('Data%d.bin',int8(i));
stuff(name)
end
In the generated C code it uses a lot of functions like emxutil to determine the size of the generated string for sprtintf.
I just want to say that i is only one digit. How can I do that?!
The followings also do not work
name=['Data',char(i),'.bin'];
Using the following also gives an error for generating code that LHS is fixed sized but RHS is varying:
coder.varsize('name',[1,14],[0,0])

If you know that it is a single digit then do not use that technique. Instead you can use
name = ['Data', char(i+'0'), '.bin']
Or if you really need to
name = 'DataX.bin';
name(5) = char(i+48);
