mtlb_toeplitz

Description

Matlab and Scilab toeplitz behave differently in some particular cases:

• With one input parameter: if this parameter is complex or is a matrix, output value of Matlab and Scilab toeplitz can be different.

• With two input parameters: if they are vectors and their first elements are not equal, Scilab returns an error but Matlab gives priority to the column element. If they are matrices, output value of Matlab and Scilab toeplitz are different.

The function mtlb_toeplitz(c[,r]) is used by mfile2sci to replace toeplitz(c[,r]) when it was not possible to know what were the operands/inputs[CUSTOM] 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_toeplitz calls:

• When called with one input, if c is a real scalar or vector mtlb_toeplitz(c) may be replaced by toeplitz(c)

• When called with two inputs, if c and r are scalars or vectors and their first elements are equal mtlb_toeplitz(c,r) may be replaced by toeplitz(c,r)

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