# How To Do Sine In Matlab?

## MATLAB users sometimes ask how to plot sin.

freq=1000; percent 1 kHz.

t equals linspace(0,5,1024)/freq, which is a percentage ranging from 0 to 5 periods over 1024 steps.

A=2; percent amplitude.

x=A*sin(freq*t*2*pi); \splot(t,x)

## How does MATLAB do the sine-theta calculation?

The sine of each element in X may be obtained by plugging Y = sin(X) into a calculator. When used to arrays, the sin function works element-by-element. The function is willing to take either actual or complicated data as input. When applied to X values that are real, the sin(X) function produces values that are real and fall in the range [-1, 1].

## How exactly does one go about creating a sine curve in MATLAB?

Produce a single cycle of a sine wave at a specified frequency.

fs = 512; percent The frequency of sampling (samples per second)

dt = 1/fs; percent seconds per sample.

StopTime is equal to 0.25 seconds, or 25 percent of a second.

t = (0:dt:StopTime-dt)’; percent seconds.

F = 60; percent Data for the sine wave’s frequency, expressed in hertz, equals sin(2*pi*F*t); Which function in MATLAB is responsible for the plotting of the sine wave? In the MATLAB sine function, the result is always sin (wt). Since the frequency w is measured in radian/second rather than f, which is measured in hertz, w will tell you the number of cycles. You may use the sin(2*pi*60*t) equivalent, which is denoted by the sind(2*pi*9.545*t), instead.

## In Matlab, how do you go about plotting a graph?

Define x by indicating the acceptable range of values for the variable x, which will be used to generate the plot for the function.

Define the function using the notation y = f. (x)

Invoke the plot command, written out as plot (x, y)

In MATLAB, how do I go about plotting a function?

Indicate the Axes for the Line Plot In order to build an axes object, use the nexttile method, and then return the object using the ax1 variable. By providing ax1 as an argument to the plot function, you may generate the top plot. By providing the axes as arguments to the title and ylabel methods, you may give the plot a title and label the y-axis. It will take many repetitions to finish the bottom plot.

## Which comes first, a radian or a degree?

MATLAB’s trigonometric functions compute normal trigonometric values in radians or degrees, hyperbolic trigonometric values in radians, and inverse variations of each function. These calculations may be performed in either radians or degrees.

## What exactly is the plot in Matlab?

When creating a graphical representation of some data in Matlab, the plot function is the one that should be utilized. When the data is plotted, it is frequently quite simple to “see” a trend, but when the numbers themselves are seen, it is far more difficult to do so.

## Can you plot a matrix with Matlab?

The plotmatrix(X, Y) command generates a matrix of subaxes that contains scatter plots that compare the columns of X to the columns of Y. In the event when X is a p-by-n matrix and Y is a p-by-m matrix, the output of plotmatrix will be an n-by-m matrix of subaxes.

## In MATLAB, what is the connection between Theta and Rho?

To figure out how y is connected to x, you need just use some elementary algebraic concepts. When you use the command polar (theta,rho), a polar coordinate plot of the angle theta vs the radius rho is produced. theta is the angle in radians measured from the x-axis to the radius vector, and rho is the length of the radius vector measured in dataspace units.

## Describe the operation of the sin function in MATLAB, please.

y will be returned with the same data type as theta if it is a fi single, a fi double, or a fi scaled double with binary point scaling. The following is an example of how the sin function uses an 8-bit lookup table to calculate the sine of a fixed-point input:

## What really happens when you use the plot function in MATLAB?

If the number of rows in the matrix is equal to the length of the vector, the plot function will plot each column of the matrix vs the vector. If the number of columns in the matrix is equal to the length of the vector, then the function will plot each row of the matrix vs the vector.

## Where can I get instructions for plotting three sine curves in MATLAB?

Create a graph with three sine curves, each of which has a little phase change relative to the others. When drawing the first sine curve, use a green line with no markings on it. For the second sine curve, draw it with a blue dashed line and put circle marks on it. For the third sine curve, just the blue star markers should be used.
