You are right, I checked and it's correct. Sometimes it's easier as it seems : )

Hi, I need to reshape a one dimensional array into three three-dimensional arrays and I wonder how to do this correctly. In the code sample below you can see how the big one dimensional array is formed from the three three-dimensional ones. But now I need to do the opposite operation. Would be...

Hi asela23 there are different ways to solve the linear system Ax = b. From your first post you I see that x and b are vectors and A is symmetric. You get x by inverting the coefficient matrix A -> x = A^-1 b. Inversion of A can be done by an iterative method like preconditioned conjugated...

Thanks feherke for the quick reply - now I also understand the error message : )

Hi all, Because of getting tired of editing ini files I wanted to write a small prog helping me. I have to make a list of several instruments and runs. I tried: set maxtape 10 set maxsite 10 for { set i 1 } { $i <= $maxsite } { incr i } { set j 0 for { set j 1 } { $j <= $maxtape } { incr...

Hi xwb, thanks for the help. I think I will use the posibility to read the elements of the type structure individually. I do not get the improved runtime for reading but I can use the structure later.
