This matlab function or the equivalent dmobjnew dmobj1 dmobj2 performs an elementbyelement subtraction of the datamatrix object dmobj2 from the datamatrix object dmobj1 and places the results in dmobjnew, another datamatrix object. I am currently making a master table from values calculated in these different sheets. The problem is that the vectors can be both positive and negative. Inputs a and b must either be the same size or have sizes that are compatible for example, a is an mbyn matrix and b is a scalar or 1byn row vector.
