s = num2str(x)s = num2str(x,precision)
num2str converts numbers to their string representations. This function is useful for labeling and titling plots with numeric values.
s = num2str(x) converts the scalar number x into a string representation s with roughly four digits of precision and an exponent if required.
s = num2str(x,prec) converts the scalar number x into a string representation s with maximum precision specified by precision.
num2str(pi) is '3.142'.
num2str(eps) is '2.22e-16'.
num2str uses sprintf. If desired, the file can be modified to change the number of digits.
