Issue ID: 13685
Summary: std.numeric.arrayShape
Product: D
Version: D2
Hardware: x86
OS: Windows
Status: NEW
Severity: enhancement
Priority: P1
Component: Phobos
Assignee: [email protected]
Reporter: [email protected]
I suggest to add to Phobos a simple function "arrayShape", that given a nD
array performs:
1) calls isRectangular (Issue 13684 ) to verify the input array is complete.
2) Returns a n-tuple of the lengths of matrix sides.
Examples:
arrayShape([1, 2]) => tuple(2)
arrayShape([[1, 2], [3, 4], [5, 6]]) => tuple(3, 2)
arrayShape([[1, 2], [3], [5, 6]]) => exception
This is useful to quickly compare the shape of nD arrays, when you need them to
be of the same sizes:
void foo(int[][] a1, float[][] a2)
in {
assert(a1.arrayShape == a2.arrayShape);
} body {}
