scicos_getvalue

xwindow dialog for Xcos

Calling Sequence

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

Arguments

: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 : :”intvec” for constant vector with integer values i.e int(x) == x : :”str” for string : :”lis” for list :

: :dim_i defines the size of the ith value it must be an 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]=scicos_getvalue("define sine signal",labels,...
     `list`_("vec",1,"vec",1,"vec",1),["0.85";"10^2";"%pi/3"])
