For an example of this function, see gain.tlc.

Note 1: Do not use this function to build the address of a parameter. For

example,

%assign paramAddr = "&%<LibBlockParameter(Gain, ...)>"

This may produce a reference to a constant number, for example &4.95 if the

value of

Gain is 4.95, and RTW is configured to inline parameter values. Use

LibBlockParameterAddr to avoid this undesirable behavior.

Note 2: Code generation exits if this function is passed a matrix parameter.

(see LibBlockMatrixParameter).

LibBlockParameterAddr(param, ucv, lcv, sigIdx)

This function returns the appropriate address of a block’s parameter. The

function works similarly to

LibBlockParameter except that its returned value

is independent of the inline parameter values configuration. That is,

LibBlockParameterAddr(Gain, "i", "", sigIdx) will return &rtP.Gain[i]

regardless if RTW is configured to inline parameter values. For an example of

this function, see

lookup2d.tlc.

Note: Calling this function will force the parameter to stay in memory

regardless of the value of

InlineParameters.

LibBlockMatrixParameter(param, rowUcv, rowLcv, rowSigIdx, colUcv,

colLcv, colSigIdx)

This function is similar to LibBlockOutputSignal, except it returns the

appropriate reference to a block’s matrix parameter. These are user control

variables, loop control variables, and signal indices for both the rows and
