Hello,
I have a struct in Matlab as follows:
Now, based on the "name" field, I would like to create a new field called "Color". This new field would have two values, "blue" or "red", depending on the names inside the "name" field. Specifically, if the names have he letters H1, H2 or H3, the color in the new field should be "blue", whether if the name has the letters H4, H5 or H6, it should be "red".
Anyone could help me with this?
Thanks in advance.
-Mikel

names={Stimuli.names};
idxBlue=contains(names,["H1" "H2" "H3"]);
idxRed =contains(names,["H4" "H5" "H6"]);
[Stimuli(idxBlue).Color]=deal("blue");
[Stimuli(idxRed).Color]=deal("red");
