mtlb_conv

Matlab conv emulation function

Description

Matlab conv and Scilab convol behave differently in some particular cases:

  • With column vector inputs: if at least input is a column vector Matlab conv returns a column vector but Scilab convol always returns a row vector.

The function mtlb_conv(u,v) is used by mfile2sci to replace conv(u,v) 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_conv calls:

  • If u and v are row vectors, mtlb_conv(u,v) may be replaced by convol(u,v)

  • If u or v is a column vector, mtlb_conv(u,v) may be replaced by convol(u,v).'

  • If u and v are column vectors, mtlb_conv(u,v) may be replaced by convol(u,v).'

Scilab convol sometimes returns values that may be rounded using clean to have a closer result from Matlab one.

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