num2str

Convert a number to a string.

Syntax

str = num2str(A)
str = num2str(A, precision)
str = num2str(A, format)

Description

Returns a string representation of the number(s) in A. With a numeric precision, controls the number of significant digits. With a string format (a sprintf-style format spec like '%6.2f'), uses that exact format.

Examples

num2str(pi)              % '3.1416'
num2str(pi, 10)          % '3.141592654'
num2str(pi, '%8.4f')     % '  3.1416'
