Removal of Nan Values from a Matrix.There are multiple methods by which we can remove Nan values from a specified matrix:.
Method 1: By using rmmissing( )
This function is used to remove missing entries or Nan values from a specified matrix.
Syntax
rmmissing(A)
Parameters: This function accepts a parameter which is illustrated below:
- A: This is the specified matrix of elements.
Return Value: It returns the matrix without missing entries or Nan values.
Example:
Matlab
% MATLAB code for remove NaN % values using rmmissing() A = [1, NaN, 2, 3 NaN, 4]; % Initializing
% of matrix % Calling the rmmissing() function over % the above matrix B = rmmissing(A) |
Output:
Method 2: By using isnan( )
This function is used to return a matrix of 1 i.e. true for the elements like NaN, and 0 i.e. false when they are not.
Syntax
isnan(A)
Parameters: This function accepts a parameter.
A: This is the specified matrix of elements.
Return Value: It returns the matrix of logical values.
Example:
Matlab
% MATLAB code for remove NaN values using isnan() A = [1, 2, NaN, 3, 4]; % Initializing of matrix
% Calling isnan() function and getting matrix % boolean values i.e. 1 or 0 B = isnan(A) % Getting a new matrix "C" without NaN values % which was originally "A" C = A(~B) |
Output:
