Power requirement calculate in image processing

Hi all,

Which command that use for measure the power consumption or requirement for our Matlab code.

http://www.mathworks.com/matlabcentral/fileexchange/11846-cdf-97-wavelet-transform/content/wavecdf97.m

For example If I use the code above to compress my image. Which command or how we know the total power consumption for this code?

Thank you Warinthorn

Do you mean "power" in the electricity sense? Or are you trying to find out the total number of CPU instructions executed to process one particular image? Or are you trying to find out what the "order of operations" ("Big-O notation") is for an algorithm?

I mean power in the electricity sense.

(If I implement this code(algorithm in electronic devices))

Many Thank

Algorithm in electronic devices... is that a reference to code generation for VHDL or FPGA purposes? Knowing the electricity consumption on (say) an Pentium 4 @ 2.2 GHz would not give you any useful information about VHDL or FPGA energy use.
