Hi,
The vector you are seeing in your result is the component wise variance of each principal component. I tried the same example and coeff variable is a 4x4 matrix for me.
Can you try with full syntax which is mentioned below:
[coeff,score,latent] = pca(ingredients)
This should give correct result.
