--------------------------
Well "hey" to you too.  How about picking a real subject line next
time?  For (a), try the plot() command.  Plot ln(x^4) for a bunch of x
values and see where it crosses a y value of 0.7.  Pretty simple - one
or two lines.

You didn't specify which TEXT BOOK! We can't help you unless you specify the book AND the publisher. And the page this problem is located at.

I cant compile a matlab function in simulink. Matlab 2012b, OSX 10.8.2, xcode 4.5.2
Hi, I haven't been able to compile a Matlab function in a Simulink model. I am using Matlab 2012b, OSX 10.8.2 and Xcode 4.5.2. I have already run the patch for Xcode 4.5.2 and also verified that SDKROOT='/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/' in the mexopts.sh file. When simulink tries to compile the function I get the error message: /usr/llvm-gcc-4.2/bin/../lib/gcc/i686-apple-darwin11/4.2.1/include/limits.h:15:25: error: no include path in which to search for limits.h Any ideas how to fix this. ...

2 * 2 * 2 * 2 or pow(2, 4)?
Hi , I hope this isn't too trivial to ask, but I'm evaluating a polynomial that involve lots of terms like x^2y^2z^3, and although I can use the power function pow(a, b), I wonder if just writing x*x*y*y*z*z*z for example wouldn't be more efficient than pow(x, 2)*pow(y, 2)*pow(z,3). Or is it all the same?

matlab in JAVA or java in MATLAB? #2
Hi guys I am now experencing a great difficulty in the interation between java and matlab. I have an objective function written in JAVA with has method return an numerical number, i call it 'profit'. The nature of this obtive function (ObjFun.java) is that it takes an parameter input, say C, with different C value, the returned profit value is different. Eventually I want to find the optimized C value which produce the maximun profit (C will be under constrains). Initially I want to use linprog or fminsearch in matlab. So I tried the command in matlab that excutes my ObjFun.ja...
