W1_A3_X shape description

In the week 1 programming assignment 3, in the implementation of the function gradient_check_n(), the comment for the argument X reads, “input datapoint, of shape (input size, 1)”.

I think it should be “input datapoint, of shape (input size, number of examples)”.

I actually tried to print out the shape from the unit test code following this cell. The shape printed (4, 3), which indicated the number of examples used in the unit test code was 3.

Hey @WinniePooh,
Thanks for your inputs. An issue has been raised to rectify this.
