Matlab r2015b includes an histogram2 function that does all the work. This function also allows several characteristics of the plot to be set. Given the joint probability density function in tabular form, determine the joint cumulative distrubution function.

Cdfplot invisibly returns a list giving coordinates of the points that have been or would have been plotted

According to the model, it seems quite likely that the state of the motor was not good. As michael hardy commented, this confirms you are thinking about the situation correctly). Generate a random sample data set from the extreme value distribution with a location parameter of 0 and a scale. The volume underneath the entire joint density, which is obviously equal to $1$;
