inputToAlgebraic

Method of mdss.

Reclassify prescribed inputs as computed algebraic outputs.

Source: src/model/@mdss/inputToAlgebraic.m

Syntax

sys = inputToAlgebraic(sys, names)
sys = sys.inputToAlgebraic(names)

Description

inputToAlgebraic moves the named signals from the input partition to the algebraic partition. The variables keep their position in the underlying signal vector and every equation that references them is untouched — they simply stop being prescribed and are solved for instead. In an mdss an “output” is just a computed algebraic variable, so the moved signals become the last entries of the algebraic block.

Use this to square an over-determined boundary set: each input turned into an algebraic adds one unknown without adding an equation, closing the gap.

The requested names must all be current inputs, and each may be listed only once; a duplicate name or a name that is not an input raises an error. After the move, checkIndexDimensions is called to confirm the index vectors are still consistent with the tensor dimensions.

Input arguments

Argument	Description
`sys`	The `mdss` model.
`names`	String array `(1,:)` of input signal names to reclassify. Must all be current inputs; duplicates are rejected.

Output arguments

Output	Description
`sys`	The model with the named signals moved into the algebraic block.

Example

sys = sys.inputToAlgebraic(["Pipe_1_m_inlet", "Pipe_3_t_outlet"]);
