Question

Resizing matrices - again!

More than few times I tried to explain that(in some cases) Prime Beta,Alpha is resizing simultaneously more than one matrices although only a single matrix is selected for resizing. I attached an AVI file (the quality sacrified to the size, sorry).



More than few times I was told that this could not be reproduced. Am I doing anything wrong here?

Radovan,

I am using the same Alpha software and tried to duplicate your steps about 6 times and the second matrix does not resize. Can anyone else report seeing the same problem? I will give your video to our quality assurance group. I don't know what's different about your system versus mine that would cause that.

Thanks for posting the video.

Our QA department was able to duplicate this, but only sometimes. Can you list the exact steps, to help them narrow it down.

Thanks,

Mona

Here it is. I must say that I do not see any unusul step here.

1. Run Prime
2. Type A:identity(50)[ENTER]
3. Type A=
4. Move the matrix A down with the mouse
5. On the right type A*A^-1[SPACE][SPACE]=
6. Click anywhere outside the result
7. Place the cursor on the right lower corner on the matrix A
8. Click and Drag it in order to resize it
9. And here we are: both matrices will resize

Sometimes you can put below the third matrice, say, again A= , or A*A^-1[SPACE][SPACE]= and click on the empty space. All the three matrices could be resized at the same time by resizing either of them

I can't duplicate in W XP Pro SP3.

We've narrowed down the issue to only happening when you click in a certain area in the worksheet. Now that we can duplicate it, our developers can fix the problem.

Thanks for all the efforts to help us track this down.

Wish that I knew where that spot is!!

In the attached image, you can see that I was working with the matrix Ch. I was shrinking it vertically. Then I noticed that all 3 matrices were shrinking at the same time. Then M' went nuts. Changed the color of Ch here and in the plot to black. Turned the plot color gray. The doc scrolled up and down by itself for several minutes, then stopped.

Then, too, the attached M' file works in M14, but not here. 2 CPUs @ 85%, but never ends...
