val_cellstr = num2cellstr( values , format = '%g' )
Utility to extend the ability of the function num2str( ... ) to convert numbers in strings. Instead of concatenating the array of numbers values into a single string, this utility generate the cell-string val_cellstr whose elements are strings each converting the corresponding numeric element of values . If passed, the input argument format allows to customize the conversion.
values ::real:: Vector, matrix or multidimensional-array of real numbers. format ::format_string:: Format string to customize the conversion from numbers to strings. It must be suitable to be used by the family of C-language derived functions *printf. If omitted, the default value is '%g'.
% Basic usage num2cellstr( 1 ) num2cellstr( [ 1 pi -1.23 inf nan 0 ] ) num2cellstr( [ 1 pi -1.23 ; inf nan 0 ] ) % Customizing the conversion num2cellstr( [ 1 pi -1.23 inf nan 0 ] , '%d' ) num2cellstr( [ 1 pi -1.23 inf nan 0 ] , '[%g]' ) % Motivating example n = 20 [x,y,z] = mdeal( cumsum( cumsum( randn( n , 3 ) ) ) ); figure( 1 ); hold off; plot( x, y, 'o-' ) text( x, y, num2cellstr( z , ' %.2g' ) ) figure( 2 ); hold off; plot3( x, y, z, '-' ) text( x, y, z, num2cellstr( 1:n ) )

The Mastrave modelling library is committed to provide reusable and general - but also robust and scalable - modules for research modellers dealing with computational science. You can help the Mastrave project by providing feedbacks on unexpected behaviours of this module. Despite all efforts, all of us - either developers or users - (should) know that errors are unavoidable. However, the free software paradigm successfully highlights that scientific knowledge freedom also implies an impressive opportunity for collectively evolve the tools and ideas upon which our daily work is based. Reporting a problem that you found using Mastrave may help the developer team to find a possible bug. Please, be aware that Mastrave is entirely based on voluntary efforts: in order for your help to be as effective as possible, please read carefully the section on reporting problems. Thank you for your collaboration.
