Thanks so much Scott and Yair. doc followed by commandwindow works out exactly as I want on the Linux version of MATLAB at school. Will try it out on the Windows version at home, though I don’t see why it should be any different.

Pravin/Scott – you can use the built-in commandwindow function to programmatically bring the Command Window into focus following the doc command.

commandwindow is a fully supported and documented function, although internally it uses undocumented/unsupported functionality.

Pravin – You can almost get this by putting a call to

doc

in your startup.m file. This forces the doc open in the last place you left it. The only problem is that it brings it to the front, so you would need to click on the command window to bring it back to focus.

Hi guys, I use the Help Browser quite frequently as I try out new functions in MATLAB. I am using the r2009a version, and would like to know if there is anything I can put in the startup.m file to have the helpbrowser appear in a closed tab next to my command window. I saved the required arrangement as a custom desktop layout, but I don’t know if there is any way to make it the default one.

Also, Chanel, you may have moved on to more interesting things, but I believe the im2bw() function should work admirably in this case.

Chanel, This would be a great question for the MATLAB newsgroup: comp.soft-sys.matlab. You should think about this the MATLAB way, which is to use vector indexing to access the matrix, rather than by element. So,

x = rand(2,3)
x(x<0.2)=0
x(x>=0.2)=1
% or
x(logical(x)) = 1

x =

    0.9572    0.8003    0.4218
    0.4854    0.1419    0.9157


x =

    0.9572    0.8003    0.4218
    0.4854         0    0.9157


x =

     1     1     1
     1     0     1


x =

     1     1     1
     1     0     1

Hi, a question about arrays???
Create an M-by-N array of random numbers (use rand). Move through the array,
element by element, and set any value that is less than 0.2 to 0 and any value that is
greater than or equal to 0.2 to 1

If you could help that would be great. Thanks

I am writing a program and I want to know how to write an integral. I want to put S=2*pi*(integral of r*dz between 0 and R) if you could help that would be great. Thanks
