Syntax

[data,parameters,frequency] = calculate(rfdataobject,parameter1,...,parameterN,format)
[data,parameters,frequency] = calculate(rfcktobject,parameter1,...,parameterN,format)

Description

example

[data,parameters,frequency] = calculate(rfdataobject,parameter1,...,parameterN,format) calculates the required parameters of the rfdata.data object, rfdataobject and returns them in a cell array, data.

[data,parameters,frequency] = calculate(rfcktobject,parameter1,...,parameterN,format) calculates the required parameters of the rfckt object, rfcktobject and returns them in a cell array, data.

Input Arguments

collapse all

RF data, specified as a handle of an rfdata.data object.

Example: rfdataobject = rfdata.data;[data,parameter,frequency] = calculate[rfdataobject] calculates and returns the cell array of data for the rfdata.data object, rfdataobject.

Data Types: char | string

RFCKT element, specified as a handle of an rfckt object.

Example: rfcktobject = rfckt.amplifier;[data,parameter,frequency] = calculate[rfcktobject] calculates and returns the cell array of data for the rfckt amplifier object, rfcktobject.

Data Types: char | string

Parameters of an rfckt object or rfdata.data object, specified as a character vector or string. Use the listparameter function to list the parameters of the specified rfckt object or rfdata.data object.

Example: rfcktobject = rfckt.amplifier;listparam(rfcktobject);You can use any of the parameter from the output of listparam in the calculate function.

Data Types: char | string

Format of output data, specified as a character vector or string. Use the listformat function to list the valid formats of the parameter values of the specified rfckt object or rfdata.data object.

Example: rfcktobject = rfckt.amplifier;listformat(rfcktobject,parameter);Lists the format of the specified parameter of the rfcktobject. You can then use this format value in the calculate function.

Example: Specify format as Real to compute the real part of the selected parameter. Specify format as none to return the parameters values unchanged.

Data Types: char | string

Output Arguments

collapse all

Data of the rfckt element or rfdata.data object, returned as an n-element cell array.

Name of the parameters in data output, returned as an n-element cell array.

Frequencies at which the parameters are known, returned as vector.
