Argmin is the value of the variable with the smallest probability.

It is usually used for imaging,

It seems that,

Many papers on images in colleges and universities in Northeast China are used in this way.

Matlab has a probability and statistics toolbox.

But the function and usage are different,

I once spent a month trying to figure out,

But because the probability is not enough,

I don't understand the toolbox.

Finally, some related algorithms are abandoned.

You can try to look it up on Google.

Pay attention to the publication of students' homework in schools such as Massachusetts Institute of Technology.

Maybe you can come across one or two programs with related functions.
