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.
