tensor v0.7.0 Matrix
Summary
Functions
Returns the n
-th column of the matrix as a Vector
Returns the columns of this matrix as a list of Vectors
Creates a square matrix where the diagonal elements are filled with the elements of list
.
The second argument is an optional identity
to be used for all elements not part of the diagonal
Builds a Matrix up from a list of vectors
Creates an ‘identity’ matrix
Returns the values in the main diagonal (top left to bottom right) as list
Calculates the Scalar Multiplication or Matrix Multiplication of a
* b
Creates a new matrix of dimensions width
x height
Returns the n
-th row of the matrix as a Vector
Takes a vector, and returns a 1×n
matrix
Returns the rows of this matrix as a list of Vectors
True if the matrix is square and the same as its transpose
Converts a matrix to a list of lists
Returns the sum of the main diagonal of a square matrix
Functions
Returns the n
-th column of the matrix as a Vector.
If you’re doing a lot of calls to column
, consider transposing the matrix
and calling rows
on that transposed matrix, as it will be faster.
Creates a square matrix where the diagonal elements are filled with the elements of list
.
The second argument is an optional identity
to be used for all elements not part of the diagonal.
Builds a Matrix up from a list of vectors.
Will only work as long as the vectors have the same length.
Creates an ‘identity’ matrix.
This is a square matrix of size size
that has the diag_identity
value (default: 1
) at the diagonal, and the rest is 0
.
Optionally pass in a third argument, which is the value the rest of the elements in the matrix will be set to.
Calculates the Scalar Multiplication or Matrix Multiplication of a
* b
.
If b
is a number, then a new matrix where all values will be multiplied by b
are returned.
if b
is a matrix, then Matrix Multiplication is performed.
This will only work as long as the height of a
is the same as the width of b
.
This operation internally builds up a list-of-lists, and finally transforms that back to a matrix.
Creates a new matrix of dimensions width
x height
.
Optionally pass in a fourth argument, which will be the default values the matrix will be filled with. (default: 0
)
Returns the sum of the main diagonal of a square matrix.
Note that this method will fail when called with a non-square matrix
