Description

The Single Point Interpolation block performs linear interpolation using the AUTOSAR Ifl_Interpolate_f32 routine. The Single Point Interpolation block performs interpolation using inputs u₁ and u₂ and a fraction source parameter f according to this equation: $$y=u_1+f(u_2-u_1)$$

You can specify the fraction source using the Block Parameters dialog box or an Input port. The Single Point Interpolation block supports software-in-the-loop (SIL) mode.

When you select the AUTOSAR 4.0 code replacement library (CRL) for your AUTOSAR model, your model replaces code that you generate for this block with a call to the Ifl_Interpolate_f32 AUTOSAR library routine.

Ports

Input

u₁ — First input signal

scalar | vector

Input signal, specified as a scalar or vector.

Data Types: single

u₂ — Second input signal

scalar | vector

Input signal, specified as a scalar or vector.

Data Types: single

f — Fraction value

scalar

Coefficient for the Ifl_Interpolate_f32 routine.

Dependencies

To enable this port, set the Source field of the Fraction parameter to Input port.

Data Types: single

Output

y — Output signal

scalar | vector

Output signal, returned as a scalar or vector.

Data Types: single

Parameters

Fraction — Fraction source and value

0 (default) | scalar

Source and value of the coefficient for the Ifl_Interpolate_f32 routine.

Specify the Source field of this parameter as one of these values.

• Dialog — Set the coefficient using the Value field of this parameter.

• Input port — Set the coefficient using the f port. The block uses the value of this port as the coefficient.

Programmatic Use
