Basic operations
Changing array shape
Transpose-like operations
(a, source, destination)
Move axes of an array to new positions.
(a, axis[, start])
Roll the specified axis backwards, until it lies in a given position.
(a, axis1, axis2)
Interchange two axes of an array.
View of the transposed array.
(a[, axes])
Returns an array with axes transposed.
(a[, axes])
Returns an array with axes transposed.
(x, /)
Transposes a matrix (or a stack of matrices) x.
Changing number of dimensions
(*arys)
Convert inputs to arrays with at least one dimension.
(*arys)
View inputs as arrays with at least two dimensions.
(*arys)
View inputs as arrays with at least three dimensions.
(*arrays)
Produce an object that mimics broadcasting.
(array, shape[, subok])
Broadcast an array to a new shape.
(*args[, subok])
Broadcast any number of arrays against each other.
(a, axis)
Expand the shape of an array.
(a[, axis])
Remove axes of length one from a.
Changing kind of array
(a[, dtype, order, device, copy, like])
Convert the input to an array.
(a[, dtype, order, device, copy, like])
Convert the input to an ndarray, but pass ndarray subclasses through.
(data[, dtype])
Interpret the input as a matrix.
(a[, dtype, like])
Return an array (ndim >= 1) laid out in Fortran order in memory.
(a[, dtype, like])
Return a contiguous array (ndim >= 1) in memory (C order).
(a[, dtype, order])
Convert the input to an array, checking for NaNs or Infs.
(a[, dtype, requirements, like])
Return an ndarray of the provided type that satisfies requirements.
Joining arrays
(arrays, /[, axis, out, dtype, ...])
Join a sequence of arrays along an existing axis.
(arrays, /[, axis, out, dtype, casting])
Join a sequence of arrays along an existing axis.
(arrays[, axis, out, dtype, casting])
Join a sequence of arrays along a new axis.
(arrays)
Assemble an nd-array from nested lists of blocks.
(tup, *[, dtype, casting])
Stack arrays in sequence vertically (row wise).
(tup, *[, dtype, casting])
Stack arrays in sequence horizontally (column wise).
(tup)
Stack arrays in sequence depth wise (along third axis).
(tup)
Stack 1-D arrays as columns into a 2-D array.
Splitting arrays
(ary, indices_or_sections[, axis])
Split an array into multiple sub-arrays as views into ary.
(ary, indices_or_sections[, axis])
Split an array into multiple sub-arrays.
(ary, indices_or_sections)
Split array into multiple sub-arrays along the 3rd axis (depth).
(ary, indices_or_sections)
Split an array into multiple sub-arrays horizontally (column-wise).
(ary, indices_or_sections)
Split an array into multiple sub-arrays vertically (row-wise).
(x, /, *[, axis])
Split an array into a sequence of arrays along the given axis.
Tiling arrays
Adding and removing elements
(arr, obj[, axis])
Return a new array with sub-arrays along an axis deleted.
(arr, obj, values[, axis])
Insert values along the given axis before the given indices.
(arr, values[, axis])
Append values to the end of an array.
(a, new_shape)
Return a new array with the specified shape.
(filt[, trim, axis])
Remove values along a dimension which are zero along all other.
(ar[, return_index, return_inverse, ...])
Find the unique elements of an array.
(array, pad_width[, mode])
Pad an array.
Rearranging elements
