i'm trying to make a color plot using a data that has (2500000) elements in it. i have to do some manipulations to sort the data in to a few histogram. but matlab has been running for more than a day and still hasn't got the result. i sould mention that for 32000 data point, the same code takes almost 2 or 3 minutes to give the color plot results. is it normal to take this much time considering 2500000 data points?
