Scilab manual >> Compatibility Functions > mtlb_dec2hex


Matlab dec2hex emulation function


Matlab and Scilab dec2hex behave differently in some particular cases:

  • With empty matrix: Matlab dec2hex returns "" but in Scilab you get [].

  • With complex inputs: Matlab dec2hex automatically removes complex part of inputs but not Scilab one.

  • Matlab dec2hex always returns a row vector but in Scilab dec2hex returns a value which have the same size as the input.

  • Matlab dec2hex can have two inputs but not Scilab one.

The function mtlb_dec2hex(D[,N]) is used by mfile2sci to replace dec2hex(D[,N]) when it was not possible to know what were the inputs 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_dec2hex calls:

  • If D is not an empty matrix, mtlb_dec2hex(D) may be replaced by matrix(dec2hex(real(D)),-1,1) if D is complex and by matrix(dec2hex(D),-1,1) else.

Caution: mtlb_dec2hex has not to be used for hand coded functions.
