checks for all nonzero elements
where matrix is a numeric matrix or literal.
The ALL function returns a value of 1 if all elements in matrix are nonzero. If any element of matrix is zero, the ALL function returns a value of 0. Missing values in matrix are treated as zeros.
You can use the ALL function to express the results
of a comparison operator as a single 1 or 0.
For example, the comparison operation
yields a matrix containing elements that can be either ones or zeros.
All the elements of the new matrix are ones
only if each element of
is greater
than the corresponding element of
.
For example, consider the following statement:
if all(a>b) then goto loop;IML executes the GOTO statement only if every element of
The following statements have the same effect:
if (a>b) then goto loop;
if all(a>b) then goto loop;
