public SDVariable lte ( SDVariable x , SDVariable y ) { return lte ( null , x , y ) ; }
Less than or equal to operation: elementwise x <= y<br>
If x and y arrays have equal shape, the output shape is the same as these inputs.<br>
Note: supports broadcasting if x and y have different shapes and are broadcastable.<br>
Returns an array with values 1 where condition is satisfied, or value 0 otherwise.

@param x Input 1
@param y Input 2
@return Output SDVariable with values 0 and 1 based on where the condition is satisfied
