Package math.matrix.expressParser

Class MatrixValueParser

  • public class MatrixValueParser
extends java.lang.Object
    Objects of this class extract a matrix from an input expression of the format: [num1,num2,...:num_i,num_i+1,....:num_j,num_j+1...: ] e.g [2,3,4:4,1,2:...] The colons represent the end of one row of values and the beginning of another.

      • scanner

        public void scanner()
             throws MatrixFormatException
        Scans a matrix value string into tokens, e.g [2,4,5:3,9.939,45.2:1,4,2] and produces an output containing the numbers and the colons in the ArrayList attribute scan. Method getMatrix then extracts the matrix from scan.
        Throws:
        MatrixFormatException - if the format of the input does not conform to that of a matrix.
