sampsizepwr computes the sample size, power, or alternative parameter value for a hypothesis test, given the other two values.

sps = power_analyze('sys','setSwitchStatus',SW) creates a structure array sps with fields and values describing the state-space matrices of model sys for the switch status defined in SW. Use the command SW = power_analyze('sys','getSwitchStatus') to obtain the SW structure array.

The script uses the autoblks.pwr.PlantInfo class xlsSysSummary method to export the analysis to an Excel spreadsheet. The script provides engine plant, electric plant, and drivetrain efficiencies. Specifically, the script includes the signal energy, and an engine efficiency histogram. The script includes the autoblks.pwr.PlantInfo class sdiSummary method to create Simulation Data Inspector power, energy, and efficiency signal plots.

December 12, 2012 - I am a little shaky on this type of analysis, but, I know that I need the mean difference between x1 and x2 ( mean(x1-x2) ), the standard deviation of the difference ( std(x1-x2) ), the significance level (alpha=.05), and the desired power (0.90). Could someone point me in the right direction? Does MATLAB have a function that can tell me the sample size needed to achieve the desired power at a given significance level, mean difference, and std of difference?
