What is the Repmat function in MATLAB?

B = repmat( A , n ) returns an array containing n copies of A in the row and column dimensions. The size of B is size(A)*n when A is a matrix.

How do you repeat a number multiple times in MATLAB?

u = repelem( v , n ) , where v is a scalar or vector, returns a vector of repeated elements of v .

  1. If n is a scalar, then each element of v is repeated n times. The length of u is length(v)*n .
  2. If n is a vector, then it must be the same length as v .

How do you intersect in MATLAB?

C = intersect( A,B ) returns the data common to both A and B , with no repetitions. C is in sorted order. If A and B are tables or timetables, then intersect returns the set of rows common to both tables.

What does length function do in MATLAB?

Description. L = length( X ) returns the length of the largest array dimension in X . For vectors, the length is simply the number of elements. For arrays with more dimensions, the length is max(size(X)) .

How do you repeat a function and time in MATLAB?

repeat( action , n ) repeats the same action n times. You can specify the input arguments in any order. That is, repeat(action,n) and repeat(n,action) both repeat the action n times.

How does for loop work in MATLAB?

There are two types of loops:

  1. for statements loop a specific number of times, and keep track of each iteration with an incrementing index variable. For example, preallocate a 10-element vector, and calculate five values:
  2. while statements loop as long as a condition remains true.

How do you find the intersection of a plot in Matlab?

If you want to find X-intercept as interpolate between 2 closest points around X axes you can use INTERP1 function: x0 = interp1(y,x,0); It will work if x and y are monotonically increasing/decreasing.

How do you find where two functions intersect?

We calculate it by solving the equation f(x) = 0 . When the graphs of y = f(x) and y = g(x) intersect , both graphs have exactly the same x and y values. So we can find the point or points of intersection by solving the equation f(x) = g(x).

How do you find the max of a row in MATLAB?

m=max(I,[],2);
