# Switches between two operations depending on a scalar value.

Note that both then_expression and else_expression should be symbolic tensors of the same shape.

k_switch(condition, then_expression, else_expression)

## Arguments

 condition tensor (int or bool). then_expression either a tensor, or a function that returns a tensor. else_expression either a tensor, or a function that returns a tensor.

## Value

The selected tensor.

## Keras Backend

This function is part of a set of Keras backend functions that enable lower level access to the core operations of the backend tensor engine (e.g. TensorFlow, CNTK, Theano, etc.).
