loadct, color table list formatting 1234 0
Started by Deleted User
This is more of a bug report than help request.&160; I have created my own custom file containing all of my colortables.&160; I've sorted them in such a way that some tables occupy indices greater than 99.&160; However, when listing the contents of the color table file, the formatting of the list does not allow for 3 digit color table indices.&160;&160; For example, the output of the command, "loadct, file='~/idl/personal.tbl'":

[need help] ENVI_GET_ROI_DATA crashed 1126 0
Started by Deleted User
&160;
Hi,
I used ENVI_GET_ROI_DATA to extract data associated with ROIs and calculate statistics of the data. The function worked fine with some ROIs but got crash, sometime,&160;and return the error message as:
"
Out of range subscript encountered: ADDR.
Execution halted at: ENVI_ROI_GET_ADDR
ENVI_GET_ROI_DATA
&160;
Those ROIs are stored as polygon type and some of them have very narrow shape.
Thank you for any suggestion to fix the problem.
V.

how to export to ascii or binary floating point 1327 1
Started by Deleted User
Hi,
I'm working with satellite data in hdf format which I'd like to bring into GIS. I've read my hdf file into IDL but can't figure out how to convert/export it to something GIS can read. I'm pretty sure I can handle an ascii file in GIS, but can't figure out how to get my data to ascii. I'm a total newbie with IDL, so any help to get me over this hump would be much appreciated.
PS- I just checked my GIS and looks like a binary floating point data file will work also.
Thanks!

Suppose we call IMSL_CONSTRAINED_NLP with an objective function func_obj and a gradient function func_grad. In the function func_grad, we call IMSL_FMINV with an objective function func_obj2 and a gradient function func_grad2 to evulate the gradient.
We would have the following error information: Attempt to call undefined procedure/function: 'func_grad2'.
