The Zip(fn,M1,M2) command applies the bivariate function f to the paired entries of the Arrays, arrays, or scalars M1 and M2.

M1 and M2 must be the same size, or scalars.  If M1 is an array and M2 is a scalar, the result will be an array the same size as M1 with the scalar M2 used as the second argument to fn at each entry.

outputoptions specify additional attributes of the result Array, like datatype.  These arguments are ignored for table-based arrays.

$\mathrm{with}\left(\mathrm{MTM}\right)\:$

$\mathrm{M1}≔\mathrm{Matrix}\left(\left[\left[1\,2\right]\,\left[3\,4\right]\right]\right)\:$

$\mathrm{M2}≔\mathrm{Matrix}\left(\left[\left[1\,2\right]\,\left[3\,5\right]\right]\right)\:$

$\mathrm{Zip}\left(\left(a\,b\right)\mapsto a+b\,\mathrm{M1}\,\mathrm{M2}\right)$
