Converting sym to string without 'matrix....' before
显示 更早的评论
Hi,
I need some help to convert a symbolic array to string.
I tried with:
syms a b c
Array = [a b c];
string = char(Array);
but it returns
matrix([[a b c]]);
Is there a way to take only the string inside ? I need set it to take '[a b c]' as string.
Thanks

Can you tell us the use case here, you just want to display it as a string?
One thing you can do is
syms a b c
Array = [a b c];
array_string = char(Array);
array_string([1:8, end-1:end]) = [];

I wonder what mat2str() would return for the symbolic case?

Tried mat2str(), but gave me this error: Error using mat2str (line 55) Input matrix must be numeric.

Is there no more convenient conversion from a symbolic (which is coming from solve) to a character vector than that using char ?

No, there is no more convenient way.
Caution: char() of a symbolic expression gives a result which is not exactly a MATLAB expression, and which is not exactly a MuPAD expression either. You should only use char() of a symbolic expression for display purposes.
If you need to generate MATLAB code from a symbolic expression, use matlabFunction(), possibly followed by func2str()

In the case of symbolic row vectors:
['[', strjoin(arrayfun(@char, Array, 'uniform', 0),', '), ']']
