Filter your help
If you are using MATLAB with a lot of toolboxes and blocksets, there is a lot of documentation available to you in the Help browser. That’s almost always a good thing, but if you’re primarily interested in just a few of your installed products the others might just be cluttering up the Help browser, making it harder for you to quickly find what you need. With the product filter, you can configure the Help browser to only show documentation from the products that you really need help for.
To set the product filter, open the Preferences dialog (File -> Preferences…) and select “Help” in the left-hand side. You can get to the help preferences quickly from the command window by running
>> preferences Help
Check the box labeled “Enable product filter”, then click on the “Select products…” button to bring up the product filter dialog.
The product filter applies to the Contents, Index, Search, and Demos tabs in the Help browser, but does not apply to MATLAB commands such as help or doc. So, for example, if you have the product filter configured to hide the MATLAB documentation, you can still bring up the reference page for the MATLAB plot function by running
>> doc plot

Hello,
I have a problem with Matlab not graphing a function. I have certain constants defined except I have variable “h” and a function “Ts”.
I have this equation:
0.13=b.*p.*A.*((Ts.^4)-(Tsurr.^4))+h.*(Ts-Tamb)*A
I want to graph that function, but I have a hard time to define “Ts” as a function, but “h” is defined as a variable as I used {syms h} as a command.
When I try to ezplot the function I get:
rror in ==> ezplot>ezparam at 372
X = ezplotfeval(x,T);
Error in ==> ezplot at 163
hp = ezparam(cax,f{1},f{2},vars,labels,args{2:end});
Error in ==> sym.ezplot at 60
h = ezplot(f.s,varargin{:});
I don’t understand the language and I need help how to plot this function implicitly.
Please can you help me?

This isn’t the best forum to get help on a question like this. I’d like to suggest that you provide as much detail as you can, and either contact technical support (http://www.mathworks.com/support/), or post on the MATLAB newsgroup (http://www.mathworks.com/matlabcentral/newsreader/).
