Matlab true emulation function


There is no Scilab equivalent for Matlab true. However, Scilab ones returns a result interpreted in an equivalent way for Scilab.

Matlab true and Scilab ones behave differently in some particular cases:

  • With a scalar input: Matlab true returns a n x n matrix of ones while Scilab ones returns a 1.

The function mtlb_true(A) is used by mfile2sci to replace true(A) 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_true calls:

  • If A is a scalar mtlb_true(A) may be replaced by ones(A,A)

  • If A is not a scalar mtlb_true(A) may be replaced by ones(A)

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