**B = sqrt( X )** returns the square root of each element of the array X . For the elements of X that are negative or complex, sqrt(X) produces complex results.

## How do you express a cube root in Matlab?

**y = nthroot(X, n)** returns the real n th root of the elements of X . Both X and n must be real and n must be a scalar. If X has negative entries, n must be an odd integer. returns the real cube root of -2 .

## How do you find the sqrt of a matrix?

<a<a

You just take square roots of each component. So it's 1 1 minus 1 1 1 0 so square root of 1 which isMoreYou just take square roots of each component. So it's 1 1 minus 1 1 1 0 so square root of 1 which is 1 0 0 square root of 9 which is 3 and then 1 1 minus 1 1 inverse.

## How do you print in MATLAB?

**How do I print (output) in Matlab?**

- Type the name of a variable without a trailing semi-colon.
- Use the “disp” function.
- Use the “fprintf” function, which accepts a C printf-style formatting string.

## How do you plot on MATLAB?

**plot( X , Y ) creates a 2-D line plot of the data in Y versus the corresponding values in X .**

- To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length.
- To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix.

## How do you reverse a matrix in Matlab?

**Y = inv( X ) computes the inverse of square matrix X .**

- X^(-1) is equivalent to inv(X) .
- x = Ab is computed differently than x = inv(A)*b and is recommended for solving systems of linear equations.

## How do you raise a matrix to a power in Matlab?

Create a 2-by-2 matrix and use it as the exponent for a scalar. Compute C by first finding the eigenvalues D and eigenvectors V of the matrix B . Next, **use the formula 2^B = V*2^D/V** to compute the power.

## How do I save a figure in MATLAB?

Click File > Generate Code…. The generated code displays in the MATLAB Editor. **Save the code by clicking File > Save As**. Generated files do not store the data necessary to recreate the graph, so you must supply the data arguments.

## How do you stop a command in MATLAB?

To stop execution of a MATLAB^{®} command, **press Ctrl+C or Ctrl+Break**.

## How do you use PLT in Python?

**Following steps were followed:**

- Define the x-axis and corresponding y-axis values as lists.
- Plot them on canvas using . plot() function.
- Give a name to x-axis and y-axis using . xlabel() and . ylabel() functions.
- Give a title to your plot using . title() function.
- Finally, to view your plot, we use . show() function.

## How do you clear in MATLAB?

To clear all variables from the current workspace, **use clear or clearvars** . To clear all global variables, use clear global or clearvars –global . To clear a particular class, use clear myClass . To clear a particular function or script, use clear functionName .

## How do you do log in MATLAB?

## What is print in MATLAB?

print( filename , formattype ) **saves the current figure to a file using the specified file format**, such as print(‘BarPlot’,’-dpng’) . If the file name does not include an extension, then print appends the appropriate one.

## What is GCF MATLAB?

fig = gcf **returns the current figure handle**. If a figure does not exist, then gcf creates a figure and returns its handle. You can use the figure handle to query and modify figure properties.

## What is return MATLAB?

return **forces MATLAB**^{®} to return control to the invoking program before it reaches the end of the script or function. The invoking program is a script or function that calls the script or function containing the call to return .

## How do you plot a graph in MATLAB?

**MATLAB – Plotting**

- Define x, by specifying the range of values for the variable x, for which the function is to be plotted.
- Define the function, y = f(x)
- Call the plot command, as plot(x, y)

## How do you create a figure in Python?

**Workflow**

- Prepare your data: usually save in the a list or Numpy array.
- Create the plot/sub-plot.
- Customize your plot: adjust the linewidth, color, marker, axes, etc.
- Show/Save plot.

## How do you clear a variable in Python?
