Hi Guys, How can I find the exact location of NaN elements in a matrix. I work with really large arrays (size 1500*200). How can I find which row has a NaN value in a column matrix or vice versa.? Thanks N 0 Comments Sign in to comment. Sign in to answer this question.Accept...

这是说明没有寻找到满足你所设定的条件的点，所以用empty matrix表示
这是MATLAB绘图比较常用的一种做法。把符合某个条件的值设为NaN，绘图时这些点就不会绘制，这样可以隐藏不合需要的那部分点。就这个例子来说，是把满足z<0这个条件的点都换成NaN，也就是说，只绘制曲面的z>=0那部分（也可以把这句换成z(z<0)=NaN;效果完全相同）。比较一下，如果没有这句：加...
NaN NaN NaN 3.4095 NaN NaN 3.0360 NaN NaN NaN 2.5295 NaN ]; I was able to find the mean using nanmean and standard deviation using nanstd for each row but how do I calculate the standard error of the mean for each column in this matrix? When ...
% in other words, columns that have at least some values that are not NaNs.
% Read in data from Excel workbook. [numbers, strings, raw] = xlsread('combined_data.xlsx') % Get first data set. Eliminate nan values. x = numbers(:, 1); x(isnan(x)) = []; y = numbers(:, 2); y(isnan(y)) = []; numPoints...
If you specify this property by using a function handle, when MATLAB® executes the callback, it passes the timer object and an event structure to the callback function. The event structure contains the type of event in the Type field and the time of the event in the Data field. If ...
