Updated

ISWHOLE True for integers(whole numbers).

ISWHOLE(X) is 1 for the elements of X that are integers, 0 otherwise. ISWHOLE(X1,X2,..,XN) returns a 1-by-N array with 1 for integers and 0 otherwise.

ISWHOLE does not check for integer data type as does ISINTEGER.

works as expected. just make sure to delete the first line -- this file has two function declarations in it.

Needs some TLC and polish; though a good utility function.

In continuation to previous remark: in ISWHOLE(X1,X2,..,XN), the arrays X1, X2,... can have different dimenions. How on earth can you vectorize ISWHOLE in that case?

Mukhtar Ullah

Dear Carlos,
You seem to have completely missed what I meant. My dear, in my first syntax ISWHOLE(X), X is an array, which means it can be a vector or matrix. My second syntax ISWHOLE(X1,X2,..,XN) is for the general case when X1, X2 ,.. XN are arrays (vectors or matices). Matlab is an array oriented language, so I don't have to write that explicitely. Matlab users get it usually.

What? Do you really think so, Ullah? It's Matlab! Check out like i said, Fibonacci.m or my roundd.m, is easy my friend... and then the input can be [X1,X2,..,XN] or a matrix...

Carlos,
If you only consider the first syntax I provide ,ISWHOLE(X), then you are right. I don't need varargin. The if part of the if-else structure is vectorized already. However, the non-vectorized else part, corresponds to the 2nd syntx, ISWHOLE(X1,X2,..,XN), which cannot be vectorized, at least with the current Matlab verions.
