    • parseShape

      public static int[] parseShape​(String shape)
      Parses Matrix shape in the form of 'mxn' where m is the number of rows and n is the number of columns.
      Parameters:
      shape - - dimensions of matrix (rows by columns) in the form of a string.
      Returns:
      A double array of length two containing the number of rows and columns respectively

    • parseNumber

      public static double[] parseNumber​(String num)
      Parses a complex number in the form of a string into its real and imaginary parts. For example, the string "2+3i" would be parsed into real and imaginary parts 2 and 3 respectivly
      Parameters:
      num - - complex number in one of three forms: a + bi, a, or bi where a and b are real numbers and i is the imaginary unit sqrt(-1)
      Returns:
      A double array of length two containing the real and imaginary parts of num respectively
