I'm trying to compare two algorithms for their amount of memory usage and power consumption during processing. I compared them with respect to processing time, but I need to measure memory usage and power. Thanks in advance for your replies.
The following code returns memory usage statistics. Note that the memory option has an impact on the execution speed.
>> profile -memory on
>> %your code
>> profreport
Can you elaborate more on power consumption and what you mean by that?
This calculation is highly dependent on the hardware circuitry. For instance, if you calculate such information on your personal computer, it does not give you any information about the VHDL or FPGA energy use. I think a better measure is the number of cpu operations or the computational complexity.
As Alireza already mentioned: Use the built-in Matlab Profiler. In a more general way you could just use the full profiler, with
profile on;
%Your code
profile viewer;
Which gives you an overlook on runtime, function calls, etc.
Also see the documentation chapter about "Performance and Memory" and its section "Memory Usage" (just in case you did not already do that).
