mtlb_fopen

Matlab fopen emulation function

Description

Matlab fopen and Scilab mopen behave differently in some particular cases:

• Scilab function returns no usable error message
• Scilab file identified does not exist in case of error but Matlab one is set to -1.
• Matlab function can work with inputs which do not exist in Scilab such as permission options...

The function mtlb_fopen(filename,permission) is used by mfile2sci to replace mopen(filename,permission) 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_fopen calls:

• If error message is not used and no error can occurs, mtlb_fopen(filename,permission) may be replaced by mopen(filename,permission,0)

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