I'm doing some work classifying images and was looking for a classifier that gives its answer in turns of a probability instead of true/false like svmclassify. Anyone have any suggestions for toolboxes that have this feature?
RVMs' (Relevant Vector Machines) output probability and if you want to use them, download Kevin Murphy's Machine Learning toolkit. Matlab doesn't have an RVM implementation as far as I know.

How can I study nonlinear dynamic systems with matlab (and without using Symulink)?
For example, how can I linearize a system around a point or how can I determine the nature of an equilibrium point?
Thanks
For example, how can I solve exercise 1 of this?
You could try one of the stiff solvers such as ode23s or `ode23tb Here's another link that might be helpful...

I suggest you can read the website Linux from Scratch and try to learn to build a Linux from source code.

how to do curve fitting ??
i tried plot(cfit,x,y) and it didn't work??
If available have a look at the Curve Fitting Toolbox. You can start it using the command cftool. Please elaborate your problem.

What are the basic working principles of an antivirus program?
it matches patterns of known viruses with each file.
for example change the executable into a histogram and compare the similarity between that executable and known viruses.
another way is to scan for design patterns such as polymorphisism and comparing those to, this can lead to false positives (in very complex apps) but also catch unknown viruses.
A antivirus reads trough all files and searches for patterns of known viruses in the files.

How can I simulate a ma(1) model with parameter =0.7 using matlab?
The Systems Identification Toolbox may have what you need.
If you need or want to do it by hand, however (homework?), I would suggest outlining the steps of what needs to be done (break up the problem in parts, starting from the definition of MA models) and asking a more detailed question when you get stuck.
