I also got the ESTPAB problem. When I tried running makeosmex to recompile mex files I got the error below.

>>
xcodebuild: error: SDK "macosx10.7" cannot be located.
xcrun: error: unable to find utility "clang++", not a developer tool or in PATH

mex: compile of ' "estcondentropy.cpp"' failed.

Unable to complete successfully.

Error in makeosmex (line 25)
mex(list(i).name);

None of the solutions on this board worked for me (e.g. changing log(2) to log(2.0) or to log(double(2)), etc.

The problem turned out to be that I have Xcode 5.0 and Mac OS10.8, which apparently does not work out-of-the-box. The solution suggested by the Mathworks support team worked for me:
http://www.mathworks.com/matlabcentral/answers/103904

After that, makeosmex compiled for me and I was able to run demo_mi.

Other than that this package looks good.

Hi Pranav,

You will need to recompile the Mutual Information toolbox for your system. Use the makeosmex.m file to do so.

Best,

Can someone please help or point me to right direction?

How to fix following error?

Undefined function 'estpab' for input arguments of type 'uint8'.

Error in mutualinfo (line 21)
[p12, p1, p2] = estpab(vec1,vec2);

Error in mrmr_mid_d (line 49)
t(i) = mutualinfo(d(:,i), f);
