getvalue - xwindow dialog for data acquisition

Calling Sequence

[ok,x1,..,x14]=getvalue(desc,labels,typ,ini)

Parameters

• desc : column vector of strings, dialog general comment
• labels : n column vector of strings, labels(i) is the label of the ith required value
• typ : list(typ_1,dim_1,..,typ_n,dim_n)
  • typ_i : defines the type of the ith value, may have the following values:
    • "mat" : for constant matrix
    • "col" : for constant column vector
    • "row" : for constant row vector
    • "vec" : for constant vector
    • "str" : for string
    • "lis" : for list
  • dim_i : defines the size of the ith value it must be a integer or a 2-vector of integer, -1 stands for undefined dimension
• ini : n column vector of strings, ini(i) gives the suggested response for the ith required value
• ok : boolean ,%t if ok button pressed, %f if cancel button pressed
• xi : contains the ith value if ok=%t. If left hand side has one more xi than required values the last xi contains the vector of answered strings.

Description

This function encapsulate x_mdialog function with error checking, evaluation of numerical response, ...

Remarks

All valid expressions can be used as answers; for matrices and vectors getvalues automatically adds [ ] around the given answer before numeric evaluation.

Examples

labels=["magnitude";"frequency";"phase    "];
[ok,mag,freq,ph]=getvalue("define sine signal",labels,...
     list("vec",1,"vec",1,"vec",1),["0.85";"10^2";"%pi/3"])
