How to perform Matlab for Supervised Classification

.

Select any image

(1) Run Linear Support Vector Machine, Kernel Support Vector Machine and Fisher Linear Discriminant Analysis (training sample of prior knowledge)

(2) Adjust parameters for different Kernel Support Vector Machines to see the result

(3) Transform data first by Principal Components Analysis and repeat 1 and 2

(4) Compare all result and show conclusion

.

I would like to perform Matlab method for the image processing with Supervised Classification (herewith refer to the attached file)

However I get some error and mistake on the programming process

Kindly please help me by provide your opinion and solution or suggestion thus I will be able to improve my computing skills
