Description
model.result().numerical().create(<ftag>,"Ray") creates a ray evaluation feature with the name <ftag>. Ray evaluations can be performed on trajectories accessed through a ray dataset.
model.result().numerical(<ftag>).getReal() returns the real result, recomputing the feature if necessary. Data is ordered such that there is one row per point, with one row containing data for all solution numbers. This is identical to (columnwise) when columnwise is false. If columnwise is true, the ordering is the opposite: each column contains the values for all solution numbers.
model.result().numerical(<ftag>).getImag(allocate,columnwise) returns the imaginary part of the complex result, recomputing the feature if necessary. If allocate is true, a zero-valued matrix is allocated even when the result is real. getImag() uses allocate true and columnwise false.
model.result().numerical(<ftag>).isComplex() returns true if the result is complex. The resulting value is a scalar, which true if any of the expressions in an array is complex valued.
model.result().numerical(<ftag>).isComplex(<outersolnum>) returns true if the result is complex for the given outer solution. <outersolnum> is applicable only for parametric sweep solutions and is the index of each outer parametric solution.
model.result().numerical(<ftag>).computeResult() returns the matrix of data that the setResult method adds to a table. The matrix includes data only, not the parameter columns, and it does not use any table-specific settings.
model.result().numerical(<ftag>).setResult() and model.result().numerical(<ftag>).appendResult() evaluates the feature and set or append the result in the table indicated by the table property.
The following properties are available:
none | dataset name
The description of the expression in expr. Is used in the automatic title.
all | fraction | number
If evaluate is fraction: The fraction of rays to evaluate.
all | first | last | manual | manualindices | interp
How to input the solution to use. manual indicates that solnum is used. manualindices indicates that solnumindices is used. interp indicates that t is used.
The times to use, for transient levels. Available when data is not parent and the underlying data is transient.
An alternative way to specify the solutions to use, allowing you to enter, for example, range(1,1,20). Applicable when looplevelinput is manualindices on a level.
String array with all | first | last | manual | manualindices | interp on each level
all on all levels
How to input the solution to use, per level. manual on a level indicates that looplevel is used on that level. manualindices on a level indicates that looplevelindices is used on that level. interp on a level indicates that interp is used on that level.
If evaluate is number: The number of particles to evaluate.
all | first | last | manual | manualindices
How to input the outer solutions to use. Applicable only for parametric sweep models. manual indicates that outersolnum is used. manualindices indicates that outersolnumindices is used.
An alternative way to specify the solutions to use, allowing you to enter, for example, range(1,1,20). Applicable when innerinput is manualindices.
solnum | solutioninfo
manual | parent
If data is a local dataset with nontrivial data, specify solutions manually or take them from the parent plot group.
new | table name
The table to use when calling setResult() or appendResult(). new indicates that a new table is created.
inner | outer | data | level1
Whether to use inner or outer solutions as columns in the table when calling setResult() or appendResult(). Applicable only for parametric sweep models. The level values (level1, level2, and so on) are the levels in the parametric sweep.
The unit to use for the expression in expr. If the old unit is not valid when the expression changes, the unit property is reset to default.
