## How do you do multiple outputs in MATLAB?

Direct link to this comment

- function [x2, x3] = squareAndCube(x)
- % This function accepts up to one input argument.
- % This function REQUIRES at least one input argument.
- %
- % This function returns up to two output arguments.
- %
- % The first output is the square of the input.
- % The second output is the cube of the input.

**What does Arrayfun do in MATLAB?**

arrayfun returns the outputs of func in cell arrays. The outputs of func can have any sizes and different data types.

### Is Arrayfun faster than for loop?

For example, I tested arrayfun vs a forloop, squaring the elements, and the speed difference was a factor of two. While this is concrete evidence that we should always use for loops instead of arrayfun, it’s obvious that the benefit varies.

**What does the function all () do in MATLAB?**

all (MATLAB Functions) B = all(A) tests whether all the elements along various dimensions of an array are nonzero or logical true ( 1 ). If A is a vector, all(A) returns logical true ( 1 ) if all of the elements are nonzero, and returns logical false ( 0 ) if one or more elements are zero.

#### Can an output have multiple inputs?

No mathematical function has “multiple outputs for a single input”. Many mathematical functions have more than one input that gives the same output.

**How do I display outputs in MATLAB?**

MATLAB calls the display function to show information about an intermediate result, such as the values, size, type, and variable name. To show the value of a variable or to show program output in the command window, use the disp function.

## How do you do a cumulative sum in MATLAB?

B = cumsum( A , dim ) returns the cumulative sum of the elements along dimension dim . For example, if A is a matrix, then cumsum(A,2) returns the cumulative sum of each row.

**What is inline function MATLAB?**

The inline command lets you create a function of any number of variables by giving a string containing the function followed by a series of strings denoting the order of the input variables. …

### Is Cellfun faster than for loop?

Direct link to this comment. For the example Tom gave, however, cellfun with string is much faster than a for loop (in answer to the original question). Elapsed time is 0.755874 seconds. Elapsed time is 0.913470 seconds.

**What is the use of CLC in MATLAB?**

clc clears all the text from the Command Window, resulting in a clear screen. After running clc , you cannot use the scroll bar in the Command Window to see previously displayed text.

#### What is the function of hold on?

hold on retains plots in the current axes so that new plots added to the axes do not delete existing plots. New plots use the next colors and line styles based on the ColorOrder and LineStyleOrder properties of the axes.

**Why is x2 not a function?**

X=2 is not a function because this represents a line parallel to y axis and passing through the point (2,0). there are infinite number of points on this line so at X=2 ,y has infinite number of values. To be a function -for any X there must be only one value of y.
