• NumericArrayQ[expr, tpatt] requires additionally that NumericArrayType[expr] match the pattern tpatt.
• NumericArrayQ[expr, tpatt, dpatt] requires additionally that ArrayDepth[expr] match the pattern dpatt.

Examples

Check if an expression is a NumericArray:

arr = NumericArray[{1, 2, 3}, "Integer32"];
NumericArrayQ[arr]

Verify type and depth:

NumericArrayQ[arr, "Integer32", 1]
