Returns x + s(y - x). This linearly interpolates between x and y, such that the return value is x when s is 0, and y when s is 1.

Where:
| Name | In/Out | Template Type | Component Type | Size |
|---|---|---|---|---|
| x | in | scalar, vector, or matrix | float | any |
| y | in | same as input x | float | same dimension(s) as input x |
| s | in | same as input x | float | same dimension(s) as input x |
| ret | out | same as input x | float | same dimension(s) as input x |
