In order to have a good understanding of the ‘ranova’ please read the official MATLAB description. This tutorial is intended for more specific design; i.e. only having within independent variables. In this example I will explain 3 -way ANOVA as you can easily adapt simpler, 2-way ANOVA, or more complicated ones using this example.

MATLAB provides some special expressions for some mathematical symbols, like pi for π, Inf for ∞, i (and j) for √-1 etc.Nan stands for 'not a number'. Use of Semicolon (;) in MATLAB Semicolon (;) indicates end of statement. However, if you want to suppress and hide the MATLAB output for an expression, add a semicolon after the expression.

T = array2table(A) converts the m-by-n array, A, to an m-by-n table, T.Each column of A becomes a variable in T.. array2table uses the input array name appended with the column number for the variable names in the table. If these names are not valid MATLAB ® identifiers, array2table uses names of the form 'Var1',,'VarN',

The Matlab function for refraction at a plane interface takes as input height y of the ray at the interface, slope 𝑢= tan𝜃, thickness of the lens, index of refraction n, and vector z, which is used to plot the ray in air (back of lens). In our case, the ray travels from the medium to air.

We can use MATLAB’s built-in dsolve(). The input and output for solving this problem in MATLAB is given below. >>y=dsolve(’Dy=y*x’,’x’) y = C2*exp(xˆ2/2) Notice in particular that MATLAB uses capital D to indicate the derivative and requires that the entire equation appear in single quotes. MATLAB takes t to be the independent variable

T = array2table(A) ! make table from array T = innerjoin(T1,T2) innerjoin T = outerjoin(T1,T2) outerjoin ! Rows and vars indicate rows and variables. tables are great for large datasets, because they use less memory and allow faster operations. *rowfun is great for tables, much faster than eg. looping matrix and vector operations/functions

Figure 2.1 where we have indicated the variables used in the Matlab code. The next task to consider is the appropriate simulation period. T is defined as the ele-mentary period for a baseband signal, but since we are simulating a passband sig-nal, we have to relate it to a time-period, 1/Rs, that considers at least twice the car-

Next we need to create a MATLAB m-file to calculate dy/dt. From the MATLAB Home menu select: New ! Function. The basic structure of a function file will appear in the editor window. Modify the file to read: function dy = f(t,y) dy = -2*y + (t>=0)-(t>=1); This creates a function that calculates the value of dy (actually dy/dt). The function is
