cputime - time1In order to obtain the computation time of a function in Matlab, you can use the built-in function tic and toc. These functions create a timer that starts when tic is called and stops when toc is called. The difference between the two values gives you the computation time.
Yes, you can use the same tic and toc functions to measure the computation time of a specific section of code. Simply place tic before the code you want to measure and toc after it. The difference between the two values will give you the computation time for that section of code.
Yes, by default, the computation time is displayed in seconds. However, you can use the toc function with an output argument to specify the unit of measurement. For example, time = toc('ms') will give you the computation time in milliseconds.
Yes, you can use a loop to run the function multiple times and measure the computation time each time using tic and toc. This can be useful for comparing the efficiency of different algorithms or for finding the average computation time.
Yes, you can save the computation time data by storing the output of toc in a variable or writing it to a file. This can be helpful for tracking the performance of your code over time or comparing it with data from other runs.
