MQL5 ReferenceMatrix and Vector MethodsManipulations

Matrix and vector manipulations

These are methods for basic matrix operations: filling, copying, getting a part of a matrix, transposing, splitting and sorting.

There are also several methods for operations with matrix rows and columns.

Function	Action
HasNan	Return the number of NaN values in a matrix/vector
Transpose	Reverse or permute the axes of a matrix; returns the modified matrix
TransposeConjugate	Transposing a complex matrix with conjugation. Reverse or permute the axes of a matrix by changing a sign of an imaginary part of a complex number, return the modified matrix
TriL	Return a copy of a matrix with elements above the k-th diagonal zeroed. Lower triangular matrix
TriU	Return a copy of a matrix with elements below the k-th diagonal zeroed. Upper triangular matrix
Diag	Extract a diagonal or construct a diagonal matrix
Row	Return a row vector. Write a vector to the specified row
Col	Return a column vector. Write a vector to the specified column
Copy	Return a copy of the given matrix/vector
Compare	Compare the elements of two matrices/vectors with the specified precision
CompareByDigits	Compare the elements of two matrices/vectors up to significant digits
CompareEqual	Perform an absolute comparison of two matrices by unfolding successive rows into one-dimensional vectors
Flat	Allows addressing a matrix element through one index instead of two
Clip	Limit the elements of a matrix/vector to a specified range of valid values
Reshape	Change the shape of a matrix without changing its data
Resize	Return a new matrix with a changed shape and size
SwapRows	Swap rows in a matrix
SwapCols	Swap columns in a matrix
Split	Split a matrix into multiple submatrices
Hsplit	Split a matrix horizontally into multiple submatrices. Same as Split with axis=0
Vsplit	Split a matrix vertically into multiple submatrices. Same as Split with axis=1
ArgSort	Indirectly sort a matrix or vector.
Sort	Sort a matrix or vector in place.
