Dear all,
I would like to subtract the minimum value of a matrix from every cell.
I am not familiar with the command window and only found that "min(Matrixname)=" gives the minimum value as an output. Could somebody help me out with the correct syntax for the subtraction?
Besides could you tell me where I could find a good starting point to learn the available command syntax?
Best Regards |

Yes that solves the problem, the matrix was created from a sheet and therefore had the mentioned lock icon. |

Any chance that the matrix values were generated by some sort of operation and they are locked by a lock icon?
If so, you can't change their values as outlined.
You'd have to set the recalculation to None via the lock icon.
Then CP's suggestions would work.
Thanks,

Thanks very much for your answer. When I tried using

the vlaues of the matrix remained unchanged without any
error message.

In LabTalk, %C is the active dataset, and a matrix can be calculated like a dataset, so the following will work
%C-=min(%C)
Alternatively, you use the name of the matrix book, like
MBook1 -= min(MBook1)
Here would be a good starting point for LabTalk
