# Create array of all NaN values - MATLAB NaN

The function computes the means after removing NaN values. For example, if X is a matrix, then nanmeanX,[1 2] is the mean of all non-NaN elements of X because every element of a matrix is contained in the array slice defined by dimensions 1 and 2. NaN Description. NaN returns the IEEE arithmetic representation for Not-a-Number NaN. These result from operations which have undefined numerical results. NaN'double' is the same as NaN with no inputs. NaN'single' is the single precision representation of NaN. NaNn is an n-by-n matrix of NaNs. NaNm,n or NaN[m,n] is an m-by-n matrix. Using unique.m function on NaNs. Learn more about unique sortrows, nan~=nan, isequalwithequalnans MATLAB.

Cody is a MATLAB problem-solving game that challenges you to expand your knowledge. Sharpen your programming skills while having fun! As standard unique does not operate on columns I didn't even realise that the example had two identical columns. I saw the problem as just remove the unique elements in each row which could potentially result in rows of different length. Hence my initial question. If you are not extrapolating that should only produce NaN values for the extrapolated values if you do not include a method designation and the 'extrap' argument, and there are no NaN values anywhere in your data, and we can’t see your data to test it, this will likely remain unsolved. Use unique to find the unique elements in the concatenated vector [x;y]. The unique function performs exact comparisons and determines that some values in x are not exactly equal to values in y. These are the same elements that have a nonzero difference in x-y.. How do I count the number of NaNs in a Vector?. Learn more about nan, array, vector, counting, count MATLAB.

I have a cell array of 10 or so elements, and the first few values are NaN. I want to display the first non NaN value in the column and assign it to a variable. how to count non nan values. Learn more about vectors, matrix manipulation, matrix array. Please go to my question where i have posted data set also with complete description of my questionas Stephen mentioned. Actually i am interpolating NaN values in text file these NaN values are only 3rd column of each text file. I search your way of interpolation in my code. Extract first non NAN value in an array. Learn more about extract, first, non, nan, values, cell, array. Hello, I have an array such as arraywNan = [ NaN NaN 16 2000 2400 3214 2955; 5211 3265 4328 NaN 3951 NaN 18]. I need "isoutlier" to find the outliers only considering the non-NaN.

• For example, unique[1 1 NaN NaN] returns the row vector [1 NaN NaN]. Use the isnan or ismissing function to detect NaN values in an array. The rmmissing function detects and removes NaN values, and the fillmissing function detects NaN values and replaces them with non-NaN values.
