Returns a matrix from an array-like object, or from a string of data.
A matrix is a specialized 2-D array that retains its 2-D nature through operations. It has certain special operators, such as * (matrix multiplication) and ** (matrix power).
([axis, out])
Test whether all matrix elements along a given axis evaluate to True.
([axis, out])
Test whether any array element along a given axis evaluates to True.
([axis, out])
Indexes of the maximum values along an axis.
([axis, out])
Indexes of the minimum values along an axis.
(kth[, axis, kind, order, ...])
Returns the indices that would partition this array.
([axis, kind, order, stable, descending])
Returns the indices that would sort this array.
(dtype[, order, casting, subok, copy])
Copy of the array, cast to a specified type.
([inplace])
Swap the bytes of the array elements
(choices[, out, mode])
Use an index array to construct a new array from a set of choices.
([min, max, out])
Return an array whose values are limited to [min,max].
(condition[, axis, out])
Return selected slices of this array along given axis.
()
Complex-conjugate all elements.
()
Return the complex conjugate, element-wise.
([order])
Return a copy of the array.
([axis, dtype, out])
Return the cumulative product of the elements along the given axis.
([axis, dtype, out])
Return the cumulative sum of the elements along the given axis.
([offset, axis1, axis2])
Return specified diagonals.
(other, /[, out])
Refer to
for full documentation.
(file)
Dump a pickle of the array to the specified file.
()
Returns the pickle of the array as a string.
(value)
Fill the array with a scalar value.
([order])
Return a flattened copy of the matrix.
()
Return self as an
object.
()
Return self as a flattened
.
()
Returns the (complex) conjugate transpose of self.
()
Returns the (multiplicative) inverse of invertible self.
()
Returns the transpose of the matrix.
(dtype[, offset])
Returns a field of the given array as a certain type.
(*args)
Copy an element of an array to a standard Python scalar and return it.
([axis, out])
Return the maximum value along an axis.
([axis, dtype, out])
Returns the average of the matrix elements along the given axis.
([axis, out])
Return the minimum value along an axis.
()
Return the indices of the elements that are non-zero.
(kth[, axis, kind, order, descending])
Partially sorts the array in such a way that the value of the element in the k-th position is in the position it would be in a sorted array.
([axis, dtype, out])
Return the product of the array elements over the given axis.
([axis, out])
Peak-to-peak (maximum - minimum) value along the given axis.
(indices, values[, mode])
Set a.flat[n]=values[n] for all n in indices.
([order])
Return a flattened matrix.
(repeats[, axis])
Repeat elements of an array.
(a.reshape)
Returns an array containing the same data with a new shape.
(a.resize)
Change shape and size of array in-place.
([decimals, out])
Return a with each element rounded to the given number of decimals.
(v[, side, sorter])
Find indices where elements of v should be inserted in a to maintain order.
(val, dtype[, offset])
Put a value into a specified place in a field defined by a data-type.
([write, align, uic])
Set array flags WRITEABLE, ALIGNED, WRITEBACKIFCOPY, respectively.
([axis, kind, order, stable, descending])
Sort an array in-place.
([axis])
Return a possibly reshaped matrix.
([axis, dtype, out, ddof])
Return the standard deviation of the array elements along the given axis.
([axis, dtype, out])
Returns the sum of the matrix elements, along the given axis.
(axis1, axis2, /)
Return a view of the array with axis1 and axis2 interchanged.
(indices[, axis, out, mode])

(device, /, *[, stream])
For Array API compatibility.
([order])
Construct Python bytes containing the raw data bytes in the array.
(fid, /[, sep, format])
Write array to a file as text or binary (default).
()
Return the matrix as a (possibly nested) list.
([offset, axis1, axis2, dtype, out])
Return the sum along diagonals of the array.
(*axes)
Returns a view of the array with axes transposed.
([axis, dtype, out, ddof])
Returns the variance of the matrix elements, along the given axis.
([dtype][, type])
New view of array with the same data.
