num2str — Number to string conversion

$\begin{rail} NumToStr : 'num2str' '(' Scalar ')' ; \end{rail}$
num2str converts a real scalar into a 1x1 string matrix. This may result in scientific notation if the scalar is particularly large or small. An error will result if the argument is not a real scalar. $\Longrightarrow$ This is not an built-in function. This function is normally loaded on start-up from the num2str.r file in the standard rlib directory. Use of the -r option, incorrectly setting the RLAB_LIB_DIR environmental variable, or modifying num2str.r may make this function unavailable.
