As an internal medicine physician (M.D.) and biomedical engineer (M.S.), I have used MATLAB since 1994 to model physiological and other control systems (Control Systems Toolbox), experiment design and statistical analysis of experimental data, linear and nonlinear parameter estimation and system identification (Statistics Toolbox, Optimization Toolbox, Global Optimization Toolbox, System Identification Toolbox), signal processing of EEGs, EKGs, and other signals (Signal Processing Toolbox, Wavelet Toolbox), and some image processing (Image Processing Toolbox), although I intend to do more medical image processing now that I need to learn it. I’ve also used the Neural Network Toolbox from time to time to do nonlinear classification, and I’ve experimented with the Fuzzy Logic Toolbox with physiologic control systems as well, since physiologic control systems are in fact ‘fuzzy’.
So you need MATLAB for just about everything in Biomedical Engineering. You could probably get along without it, but only if you really restricted what you want to do to your own software that you would have to write to emulate what MATLAB already does.

Doctor Strider,
I know this is slightly off-topic but I'm a bit curious about why you called out the release R2015a documentation for FFT. Did you call that out because you prefer that version of the documentation to the R2015b version of the doc, because you're using R2015a and so that's the version of the documentation to which you refer most frequently, or for some other reason?

Nothing is really ‘off topic’ on Answers! I’m using R2015b, and I already bought R2016. I like it because the code between the first two plot figures is easier to interpret and use in ‘real world’ applications, particularly the way the frequency vector is coded for the plot (using linspace). It’s then easy to create an index vector from it for the transformed data (as 1:length(f)). I use it as a basis of my answers here, and also refer people specifically to that code as ‘the code between the first two plot figures’. The later documentation is (to my reading) less obvious. Mayhap I’m just used to the format of the previous versions, since I’ve been using them as long as I have.
