I have a worksheet in excel that contains the following data:
17 rows x 5 columns of data - the first row contains the title 3 of the variables (names of 3 different people), meanwhile column 1 contains the title for the 16 different possibilities. the internal matrix, which ends up being a 16x4, contains the statistic. I import the data into Matlab, but don't know if i should import as a matrix, cell array, or dataset. From there, how do I perform PCA? I want it to contain the names of the variables.
So far, I've performed this:
>> coeff = princomp(Cocktail1)
0.0453 0.9976 0.0500 -0.0130
0.4413 -0.0662 0.8831 -0.1453
0.5300 -0.0067 -0.1275 0.8383
0.7227 -0.0172 -0.4489 -0.5253
However, the problem is it does not show me titles of the variables.
