Is it just me, or is the most recent poll now broken?

I noticed a couple new replies show up on the recent poll a day or so ago, but since then, the page can't be loaded anymore in any browser I've tried.

Matlab full support for python?

Is MathWorks going to spend 5 years starting in 2024 making Python the #1 supported language?

I'm not sure it's authentic information, and am looking forward to a high level of integration with python.

What Should I Opt For MY SQL?

Hello, all!

This is my first post after just joining this discussion, so please forgive me and provide kind assistance if I have posted to the wrong subsection!

I have a good interest in learning sql server course and right now I am taking help from various platforms like https://www.coursera.org/ https://www.udemy.com/

Also I have a doubt that is it a good option to learn from platforms like this or I should go for some sql server online training . I have searched for the solution of my queries in various above platforms which helped me up to some extent only as it was not directly given by any expert or trainer.

Hoping in getting a quick response

Thankyou in advance.

Just for Fun and Curiosity: Guess the MATLAB Compile Threshold on Windows

Recently, I came across a post about the JIT compiler on this Korean blog. In the post. The writer discussed the concept of the "Compile Threshold" and how it is calculated.

"The JVM accumulates the number of calls for each method called and compiles when the number exceeds a certain number. In other words, there is a standard for checking how often it is called and then deciding, 'It is time to compile.' This standard is called the compilation threshold. But what is this and why should it be used as a standard?"

The concept of the "Compile Threshold," as used above, seems to be more commonly associated with Tracing just-in-time compilation.

The writer used the simple Java code below to calculate the threshold.

for (int i = 0; i < 500; ++i) {
  long startTime = System.nanoTime();
  for (int j = 0; j < 1000; ++j) {
 	new Object();
  }
  long endTime = System.nanoTime();
  System.out.printf("%d\t%d\n", i, endTime - startTime);
}

Since the MATLAB execution engine uses JIT compilation, I just wanted to perform the same experiment that the writer did.

I experimented using simple codes based on the code in the blog. I iterated a function 500 time using for-loop and calculated the execution time for each iteration using tic and toc. Then I plotted the execution time for each loop as blow. First five execution times are much higher than followings (10 times!) The test is very rough so I am not sure that I can conclude "MATLAB has Compile Threshold and it is 5!" but this value is actually correct ;-)

t0 = 0;
tfinal = 10;
y0 = [20;20];
timeToRun = zeros(500,1);
for i = 1:500
    tStart = tic;
    [preypeaks,predatorpeaks] = solvelotka(t0, tfinal, y0);
    tEnd = toc(tStart);
    timeToRun(i) = tEnd;
end

Do you use VS Code for writing MATLAB Code?

VS Code Extension for MATLAB was introduced back in April and has been downloaded 75K times since. Do people here use VS Code for writing MATLAB code?
