I have a table called "diagramoptions". This table has 2 columns. With the name Key and Value. For example i want to know the value from number_of_plots. How can i get the number 4? See attachment Picture
My idea: I search the row index of the variable number_of_plots. -> then i try to get the right cell -> (row_index,2) the number 2 is the second column in my table. The return value should be 4.
I tried a lot without any results:
test_value2 = diagramoptions(3,1)% I know it works but it is hardcoded
test_value3 = diagramoptions(:,{'Key'})
thank you

colorval = diagramoptions{3,2}
Your table will be a cell of size 8x2, to pick number of plots you have to give index (3,2) as it's value falls in the index.

Philipp, if your key values are always text, turn them into the row names of the table. Then, to use KSSV's example, you can just do this:
HarryAge = T.Age('Harry')
Even if you don't do that, you may find that
T.Age(strcmp(T.Name,'Harry'))
is simpler than converting the table to a cell array. Hope this helps.
