- Removing NaNs from vectors in MATLAB - Stack Overflow
The most efficient solution for memory management and speed is to remove values from your existing arrays using logical indexing, rather than creating new arrays xn = isnan(x); yn = isnan(y); % find the locations of the NaNs x(xn | yn) = []; % delete elements from x that are NaN in x OR y y(xn | yn) = []; % delete elements from y that are NaN
- MATLAB: How To Efficiently Remove NaN Elements from Matrix
function data_out = remove_nan (data_in, remove_dim) %remove row or col from the data_in if there is a NaN element % e g , data_in =[1 2 3 4 NaN; 1 2 3 4 5; 1 2 3 NaN NaN] % from this data remove col 4 and 5 such that data_out=[ 1 2 3; 1 2 3; 1 2 % 3] if nargin==1 col_loc=any(isnan(data_in),1); data_in(:,col_loc)=[]; data_out=data_in; elseif

- Removing NaN in Matlab: A Quick Guide for Beginners
To eliminate rows that contain any NaN values, combine `any` with logical indexing For example: Here, the command `any (isnan (matrix), 2)` checks each row for NaNs and returns a logical column vector The tilde (~) operator negates this, so only rows without NaNs are retained in `cleaned_matrix`
- ignore NaN value in the matris - MATLAB Answers - MATLAB Central
The ‘omitnan’ or 'omitmissing' flags simply delete the NaN values before performing the calculation If you are doing row-wise or column-wise calculations, that would likely be your best option as well, the doing the operation on each row or column in a loop
- Solved: remove nan in Matlab - SourceTrail
Handling and removing NaN values in a MATLAB vector or matrix is a common routine process in data analysis Often, the NaN values are inconsequential to the rest of the data and can be removed without affecting the integrity of the research or analysis Here are some methods you can use to remove NaN elements from an array
