# Finding the minimum : Step 1, apply heat. Step 2, wait for the function to cool off. Step 3, enjoy.

Hi everyone! Today I will show you a cool method to find the minimum (or maximum) of a function , where A could be a subset of the reals or of the complex numbers. So, let’s say that you want to find the minimum of This function has a complex landscape. and of course it’s easy to see the where the global minimum is and … Continue reading Finding the minimum : Step 1, apply heat. Step 2, wait for the function to cool off. Step 3, enjoy.

# Vect tip of the week : Summing it up

Hi everyone! For this vect tip of the week, we will see how we can compute weighted sums quickly. Those are sums of the form, where are the numbers that we want to sum and are the weights. Let’s start from simple sums where the weights are all one, . In Matlab, that can be done in many ways. First of all, one might be tempted … Continue reading Vect tip of the week : Summing it up

# Developing ideas in Matlab : You are doing it right!
