# Write a user-defined matlab function that determines the unit vector in the direction

The input arguments V and U are the vectors to be multiplied. Let us consider float division first. We consider those in the next section. For a complete listing of the functions available, see http: We begin with the simplest functions. First, we need to consider how to create our own functions. Next, we learn how to express this equation as a new function, which we can call with different values.

Before we get to solving equations, we have a few more details to consider.

Next, we consider evaluating functions on arrays of values. We often need to make functions in our codes to do things. That is why we see the error above.

There are a few ways to achieve that. One is to "cast" the input variables to objects that support vectorized operations, such as numpy. The syntax is lambda var: I think these are hard to read and discourage their use. Here is a typical usage where you have to define a simple function that is passed to another function, e.

You might do this so you can integrate the wrapped function, which depends on only a single variable, whereas the original function depends on two variables. You can create default values for variables, have optional variables and optional keyword variables. In this function f a,ba and b are called positional arguments, and they are required, and must be provided in the same order as the function defines.

If we provide a default value for an argument, then the argument is called a keyword argument, and it becomes optional. You can combine positional arguments and keyword arguments, but positional arguments must come first.

Here is an example. In the second call, we define a and n, in the order they are defined in the function. Finally, in the third call, we define a as a positional argument, and n as a keyword argument.

If all of the arguments are optional, we can even call the function with no arguments. If you give arguments as positional arguments, they are used in the order defined in the function.This is an introduction to R (“GNU S”), a language and environment for statistical computing and graphics.

R is similar to the award-winning 1 S system, which was developed at Bell Laboratories by John Chambers et al. It provides a wide variety of statistical and graphical techniques (linear and. 1 Overview. Gmsh is a three-dimensional finite element grid generator with a build-in CAD engine and post-processor.

Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities. About the Technical Reviewer. Eric Evenchick is an embedded systems developer with a focus on security and automotive systems.
