在 MATLAB Online 中打开

matrix=double(matrix); % where matrix is the matrix of which you are trying to calculate the mean of
matrix(matrix>185)=NaN;
Result=mean(matrix(:),'omitnan') % mean along all dimensions
result=mean(a,1,'omitnan') % mean along columns
result=mean(a,2,'omitnan') % mean along rows
result(~isnan(result)) % to omit NaN values from the result
