function opoutsize = FA_SZ_OPMINUS(in1size,in2size)
// function opoutsize = FA_SZ_OPMINUS(in1size,in2size)
// -----------------------------------------------------------------
// Returns the size of the output computed by OPMINUS operator.
//
// Assuming:
// size(in1) = [in1r,in1c]
// size(in2) = [in2r,in2c]
// size(out) = [outr,outc]
//
// we have the following combinations:
// in1 in2 outr outc
// -----------------------
// S S in2r in2c
// S M in2r in2c
// M S in1r in1c
// M M in1r in1c
//
// Where S means that the input is a scalar
// and M means that the input is a matrix.
//
// Input data:
// in1size: size of input number 1. It is an array of 2 strings.
// The first string specifies the number of rows.
// The second string specifies the number of columns.
//
// in2size: size of input number 2. It is an array of 2 strings.
// The first string specifies the number of rows.
// The second string specifies the number of columns.
//
// Output data:
// opoutsize: size of output. It is an array of 2 strings.
// The first string specifies the number of rows.
// The second string specifies the number of columns.
