Member Function Documentation

function char jsonobj = Util.matrixToJSON ( double value )

static

Takes a matrix and returns a JSON representation as JSONObject with the fields "dim" and "values".

The elements are stored inside the values array as double values, iterating through the (multi-dimensional) matrix in the order of the dimensions given in "dim". For a simple matrix this is a column-wise from left to right storage.

Parameters

value A double matrix

Return values

jsonobj A string representation of a JSON object

Here is the caller graph for this function:

function Util.saveRealMatrix	(	mat,
		file,
		folder
	)

static

Stores a real double matrix in little endian format.

The first 64bits are used to encode the row and column numbers as int32, then the next bytes contain rows*cols*8bytes of double values. The matrix is addressed linearly in a row-wise fashion, i.e. first row, second row ...
