sprintf

Format data into a string.

Syntax

s = sprintf(format, A, ...)
[s, errmsg] = sprintf(format, A, ...)

Description

Returns a string created by formatting the input arguments according to the C-style format specification. Supports %d, %f, %e, %g, %s, %c, etc. with field-width and precision modifiers.

The optional second output errmsg contains a formatting error message (or empty string if formatting succeeded).

Examples

sprintf('%d items at $%.2f each', 12, 3.5)   % '12 items at $3.50 each'
sprintf('%5d', [1 2 3])                      % '    1    2    3'
