Detailed Description

First element of a named LQN container matching a name.

Port of matlab/src/api/infer/infer_lqn_findbyname.m. No JAR counterpart.

MATLAB walks a cell array of LQN element handles and returns the first whose .name equals the argument, or [] when none does. The handle itself belongs to the LayeredNetwork model layer, which this phase of the port does not carry, so what crosses is the lookup: the container is the name list (LayeredNetworkStruct.names, the same list infer_lqn_getobs indexes) and the result is the POSITION of the match, which the caller uses to index whatever parallel array holds its elements.

The MATLAB is a linear scan returning the FIRST match, and duplicates are not diagnosed; the port keeps both properties, since an LQN with two elements of one name resolves consistently between the two implementations only if they agree on which one wins.

ARITHMETIC: none. String comparison only, so the function is not templated on the number type and is usable from every instantiation.
