Hello
During my calculations I do need to calculate inverse matrices, however, sometimes a pseudoinverse matrix needs to be calculated. When this happens, a pop-up window appears, informing about the fact, that pseudoinverse matrix has to be calculated (X-abort calculation, OK-continue), and the whole calculation is interrupted. I am always OK with this, so is there a way (or C command) to stop this pop up window appearing (like automatic OK response), and just leave code to continue?
Thanks.

Without seeing your code, hard to know what was wrong,
did you look up these examples and see if they are usful?

Thanks for advice, tried it with
zaklWeight = field * loess;
zaklTransp = zaklWeight * tField;
inverse=zaklTransp.Inverse();
inverField = inverse * field;
weighted = inverField *loess;
coef = weighted * signal;
The windows did not show up, however, results of calculations were not right (in fact, all are 0). Is my code wrong (as usual) or am I missing something?

from script window, run
ed.open(minverse)
and then you will see the code in the minverse X-function in code builder. As you can see, it simply call the Inverse() method of the matrix class. So your best bet is not to use this X-Function with LT_execute and use the Origin C code directly.

Hopefully this will be enough:
//:calculation.//
zaklWeight = field * loess;
zaklTransp = zaklWeight * tField;
BOOL in;
in = LT_execute("minverse im:=[MatrixValues]Fields*Transp om:=[MatrixValues]Inverse;");
inverField = inverse * field;
weighted = inverField *loess;
coef = weighted * signal;
lowercase name is matrix name
(Matrix<double> inverse(inverseMl), Matrix<double> zaklTransp(zaklTranspMl)).
uppercase name is matrix layer name
(int matindex8 = MatrixValuesMp.AddLayer("Inverse"), int matindex7 = MatrixValuesMp.AddLayer("Fields*Transp"))
It works perfectly most of the time, and results seem to be all right. It is only, that sometimes the program stops due to pseudoinverse matrix attention window. I have not noticed problems with values, matrix dimensions. |

Can you put down a few lines of code to show?
