Dear
I would like to write come text in a simple plot using latex codification
The plot is here
The text in plot is code as follows:
text(x0 ,y0-(i-1)*dy,sprintf('$$c_{[\rho_{e}]_w^m}$$= %.3f',b(i)), ...
'Interpreter', 'latex', ...
'fontsize', 10);
Why dose the subscript of c is not the greek letter rho?
thanks in advance

Ran in:
Because sprintf interprets '\r' as a carriage return. Use '\\r' instead.
text(.1,.5,sprintf('$$c_{[\\rho_{e}]_w^m}$$= %.3f',18.556), ...
'Interpreter', 'latex', 'fontsize', 10);
