larray.ndtest¶

larray.ndtest(shape, start=0, label_start=0, title='', dtype=<class 'int'>)[source]¶

Returns test array with given shape.

Axes are named by single letters starting from ‘a’. Axes labels are constructed using a ‘{axis_name}{label_pos}’ pattern (e.g. ‘a0’). Values start from start increase by steps of 1.

Parameters:

shape : int, tuple/list of int

Shape of the array to create. An int can be used directly for one dimensional arrays.

start : int or float, optional

Start value

label_start : int, optional

Label index for each axis is label_start + position. label_start defaults to 0.

title : str, optional

Title.

dtype : type or np.dtype, optional

Type of resulting array.

Returns:

LArray
