Cleanroom gowns are required inside the cleanroom. Other areas of the cleanroom may require further protective equipment.

MatLab is one of the greatest and most helpful tools for doing graphs, filtering data, etc. Learn how to use it by going on the tutorial.

## ece180 matlab: Multiple figure windows

The topics below are the most important topics selected from the result of students' survey. This tutorial is for those who have never touched matlab before or need some review for matlab. Created by The MathWorks, MATLAB allows easy matrix manipulation, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs in other languages.

The rows of the output array X are copies of the vector x; columns of the output array Y are copies of the vector y. The Help function is the most useful function in Matlab.

## Introduction: Plotting Data Using MATLAB

It lists all primary help topics in the Command Window. This command displays M-file help, which is a brief description and the syntax for functionname, in the Command Window. The output includes a link to doc functionname, which displays the reference page in the Help browser, often providing additional information. I think that doc link is the most useful link in Matlab.

It should contains all you want to know. General Information Information about cleanrooms, metal thermal properties and more. Photolithography Resources Information on photolithography procedures and materials. Types of Wafer Substrates A wafer after cleanroom fabrication, ready to be processed into individual parts and packaged. Related Journals Above is a link of several journals related to microfabrication and nanofabrication.

Vectors, matrix and arrays Setting up a vector or array One dimension arrays and vectors are almost the same in Matlab. You can use either vector or array form to store variables. Each is an array filled with either zeros or ones.

To make an operation work on an array, just add a dot before the normal operator. You don't need to set a for loop like in other programming languages to calculate the value of each element in b.

Matlab will do it itself. The most common functions for graphing are; plot, stem, polar, subplot, mesh, meshc, surf, surfc , and hold on. Plot and stem: The format for these is the same.

## Description

The difference is: plot will plot a continuous graph; stem is for the discrete graph. In EcEn , to graph the signal of an antenna, using a polar function is useful. Similar to plot and stem commands, the format for a polar graph is: polar x,y.

In this case, x probably is always an angle with a range of 0 to 2pi. In EcEn , it's required to plot a 3D graph of the probability with two variables. There are many useful functions that can simulate 3D graphs depending on which one you need.

It will plot one or more lines in three-dimensional space through the points whose coordinates are the elements of X1, Y1, and Z1. The difference is that these two functions will output a surface graph instead of only the connections of the dots.

So, if you want a mathematical formula of a derivative, use a calculator or another program. Derivative Matlab is able to do differences and approximate derivatives, the basic function is diff.

## Step 1: Opening the Program

For example, diff X,2 is the same as diff diff X. Matlab can also approximate implement integrals. There are many functions that can do this, such as: cumsum, trapz, quad, etc.

The cumsum function is the most useful one. It returns the cumulative sum along different dimensions of an array.

If A is a vector, cumsum A returns a vector containing the cumulative sum of the elements of A. If A is a matrix, cumsum A returns a matrix the same size as A containing the cumulative sums for each column of A. Before we look at a convolution, let's first simulate two very useful functions: the delta function and step function. We can use long arrays storing zeros and ones to approximately simulate those two functions.

Help and look for function The Help function is the most useful function in Matlab.

## Step 1: Create the random variable

A very convenient tool of MATLab 7. First, type "funtool" in the Command Window like this: Then, 3 windows Figures will show up click image to enlarge : These three images are the basis of the "funtool" function click images to enlarge : Figure 1: It is the graph of function f which will be defined in Figure 3.

Figure2: It is the graph of function g which will also be defined in Figure 3.

It may shift, shrink or enlarge the function f. The result plot will show up in Figure 2 or Figure 3.
