Briefly I want to execute
syms x
f = x
fplot(f,'b','LineWidth',2)
but a little fancier. I want the specification to be a string that I just can add. For instance:
syms x
f = x
str = ['b','LineWidth',2];
fplot(f,str)
Unfortunately this outputs an error

Store your options as a cell array and turn it into a comma-separated list when you call fplot.
syms x
f = x;
options = {'b','LineWidth',2};
fplot(f, options{:})

May be you can consider using like below.
syms x ;
f = x ;
h = fplot(f) ;
h.LineWidth = 2 ;
