Dear Madam or Sir,
I have read the file and I have already experience with the Matlab bioinfo toolbox. Moreover, as a mathematician I am familiar with the mathematical background. Therefore, the task could be solved quickly.
Just to make sure, the pdf contains a second task which does is not a matlab task. In the second part, a mathematical statement has to be proofen. My bid does not include this, but I can do it easily as well.
Best regards
