Dear list,
I have the following problem when coding in Octave/Matlab. After reading
a string from an external file into a variable, like x=fscanf(...)
resulting in x='string' how can I use this variable content as an
lvalue, like x.a='something', where x is replaced by its string value,
resulting in string.a='something' instead of x.a='something'.
For functions calls eval() can be used but what about string
substitution? BTW: We are writing som general software in Matlab/Octave
and are planning to use eval() extensively in loops. How slow it is
compared to fixed function calls?
Thanks
