Dynamic 1-D lookup

Interpolates a one-dimensional table whose breakpoints and values arrive through input ports.

Behavior

y = (1 − f) values[k] + f values[k + 1] using connected breakpoints. The worked example connects this operation to signals in Lemonergy Studio.

Connected concepts

Limits and interpretation

  • Shapes and element types are explicit. Values must be finite; automatic reshaping and unit conversion are not performed.
