Optimize Matlabe Code

Dears,

I have matlab code, which used pretrained model to classify images.
I used cross validation as well as other functions.

The code is very very slow

although there is no training and finetuning.
the current code pass the image to pretrained model and predict the values without any training process.

I need some one to trace the code and re-write it in the way that optimize the time
keep in the consideration the current logic of the code should be not changed.

I need this to be done in 1 day
my budget is 25 $
Thanks.
