mtlb_realmin

Matlab realmin emulation function

Description

Scilab equivalent for Matlab realmin is number_properties but not all cases are implemented:

• Scilab equivalent for Matlab realmin or realmin(‘double’) is number_properties(“tiny”).
• There is no Scilab equivalent for Matlab realmin(‘single’)

The function mtlb_realmin(prec) is used by mfile2sci to replace realmin(prec) when it was not possible to know what was the input while porting Matlab code to Scilab. This function will determine the correct semantic at run time. If you want to have a more efficient code it is possible to replace mtlb_realmin calls:

• If prec is equal to “double” mtlb_realmin(prec) may be replaced by number_properties(“tiny”)

Caution: mtlb_realmin has not to be used for hand coded functions.
