" ... very useful for teaching in an Instrumentation course for M.Sc postgraduates in analytical chemistry. The sequence of the topics and the explanations are very clear."
"[Y]our web site has such excellent content...."
"I tried the demo version of SPECTRUM and I think is a very useful tool for the introduction of signal processing to analytical chemistry students."
" ... a splendid program."
"I have been reviewing your webpage on signal processing
and am very impressed with the clarity of the presentation."
"...really clear and concise."
"Thanks...for your excellent code."
"Congratulations on a very useful and rather easy tool."
"Thank you for developing such a nice tool."
"Your Interactive Peak Fitter ... is very helpful.""I found your Peak Fitter program to be incredibly useful for some work I am doing...."
"Your peak finding and fitting scripts ... turned out handy in analyzing my research data."
"I appreciate all the work that must have gone into the PeakFit matlab coding. I've been using it for a couple of weeks, now, and it is becoming extremely useful."
"Thank you for your Matlab function findpeaks(). It is quite literally EXACTLY what I was looking for and far better than I could have hoped."
"Thank you so much for designing and creating MATLAB code for scientists! It's such a great resource to have code on MATLAB Central. I really appreciate your efforts.""Thank you for making available your absolutely superb Peakfinder software. It is a snap to use...." "Wonderful program."
