[source] -
Return the string representation of an array.
Parameters: arr : ndarray
Input array.
max_line_width : int, optional
The maximum number of columns the string should span. Newline characters split the string appropriately after array elements.
precision : int, optional
Floating point precision. Default is the current printing precision (usually 8), which can be altered using
set_printoptions
.suppress_small : bool, optional

precision
, if the precision is 8 then numbers smaller than 5e-9 are represented as zero.Returns: string : str
The string representation of an array.
