subtract(x1: array, x2: array, /) array

Calculates the difference for each element x1_i of the input array x1 with the respective element x2_i of the input array x2. The result of x1_i - x2_i must be the same as x1_i + (-x2_i) and must be governed by the same floating-point rules as addition (see add()).

  • x1 (array) – first input array. Should have a numeric data type.

  • x2 (array) – second input array. Must be compatible with x1 (see Broadcasting). Should have a numeric data type.


out (array) – an array containing the element-wise differences. The returned array must have a data type determined by Type Promotion Rules.
