I want to paste a small matrix into a large matrix and I have done
this several times before, but suddenly I've met the wall...
The two matrises
DOSETEMP FLOAT = Array[493, 300]
DOSETEMPFULL FLOAT = Array[512, 512]
and I want to do this:
doseTempFull[xstart:xslutt,ystart:yslutt]=doseTemp
print, xstart,xslutt,ystart,yslutt
Gives me
19 511 100 399
This works ok:
doseTempFull[19:511,100:399]=1
or
doseTempFull[19:511,100:399]=doseTemp
but the real code do not work:
doseTempFull[xstart:xslutt,ystart:yslutt]=doseTemp
This gives me the typical error:
% XMANAGER: Caught unexpected error from client application. Message
follows...
% Subscript range values of the form low:high must be >= 0, < size,
with low <= high: DOSETEMPFULL.
What is going on here? Writing the values works, but the variables
with the same values don't....
Please give me the obvious explanation that I cannot see.
Best regards
Ellen

I would like to see not a PRINT of these four
variables, but a HELP. I still think these are
not scalars, but vectors.
Help, x1, x2, y1, y2
Cheers,
David

Ellen,
Try pulling this section of code out of your application and into a
stand-alone procedure. I have no idea why this would happen, but
maybe XMANAGER is to blame? If true, the bug is with XMANAGER and the
GUI side of IDL, if not, the bug is much more sinister. Just my two
cents.

Thank you for helping me finding the right focus here. I had focus on
the fact that the variables were integers, not float or string and
then I forgot to check wether it was scalars not vectors. I had been
using the WHERE function to find the y values.... And also I had the
code two similar places with this type of code and it turned out that
I kept debugging the first after this was fixed and overlooked that
the line number where the error actually occured had changed....
Arg ...
Thank you so much for pointing me back on the road!
