divide struct field by a scalar
Hello, as the title on the post says, I have a struct S which the type of one of its fields is double ('value'): I am wondering how I could divide all of the elements stored in S.value by a scalar, call it 'max'. The only thing I could do is getting back an array of the elements: values = [S.value]/max; That di... 23 Jun 2010 13:57

Writing structs to XML-file
I am new to Matlab, Java, XML and all that stuff... What I need to do is create an XML-file from data I have in a struct. It should look like this, for example <person id="ID_stored_in_struct"> <plan selected="yes"> <act type="home" x="598954.1482461237" y="5286325.283287849" start_time="00:00:00" end_time="07:... 29 Jun 2010 17:23

Sorting cell array
Hi, I need to sort a n by 2 cell array along the second dimension. The first dimension contains structures and the second dimension contains a numerical value. I want to sort my structures by their corresponding numerical value, so in other words, I want to sort my array by the second dimension. Please let me kno... 23 Jun 2010 12:50

SymHydraulics: temperature effects
Hi Edoardo, I am facing similar problems while modeling a heat exchanger in simscape (see http://www.mathworks.com/matlabcentral/newsreader/view_thread/284135#756748 ). I would agree with you to add only the temperature as an across variable, without adding any corresponding trough variable. As far as my understa... 1 Jul 2010 12:12

Matlab integrate to Xilinx FPGA
I am new to Matlab and Xilinx. I used Matlab r2009a (not Simulink) to write codes for image processing. Is there any way to integrate the Matlab codes (it would be better if it can integrate directly) as a reference design into a Xilinx embedded board? I found out that I can - write HDL code by hand - using S... 23 Jun 2010 04:04
