  description: ['Create a new matrix or array with the difference of the passed matrix or array.', 'Dim parameter is optional and used to indicant the dimension of the array/matrix to apply the difference', 'If no dimension parameter is passed it is assumed as dimension 0', 'Dimension is zero-based in javascript and one-based in the parser', 'Arrays must be \'rectangular\' meaning arrays like [1, 2]', 'If something is passed as a matrix it will be returned as a matrix but other than that all matrices are converted to arrays'],
