Examples of cern.colt.matrix.DoubleFactory2D.make()

cern.colt.matrix.DoubleFactory2D.make()
Constructs a matrix with the given cell values. values is required to have the form values[row][column] and have exactly the same number of columns in every row.
The values are copied. So subsequent changes in values are not reflected in the matrix, and vice-versa. @param values The values to be filled into the new matrix. @throws IllegalArgumentException if for any 1 <= row < values.length: values[row].length != values[row-1].length.
