matlab nanmean

y = nanmean(X,vecdim) returns the mean over the dimensions specified in the vector vecdim.The function computes the means after removing NaN values. For example, if X is a matrix, then nanmean(X,[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.

y = nanmean(X,vecdim) 은 벡터 vecdim에 지정된 차원을 따라 평균을 반환합니다. 이 함수는 NaN 값을 제거한 후 평균을 계산합니다. 예를 들어, X가 행렬인 경우 행렬의 모든 요소가 차원 1 및 차원 2로 정의된 배열 슬라이스에 포함되어 있기 때문에 nanmean(X,[1 2])는 X에서 NaN이 아닌 모든 요소의 평균입니다.

y = nanmean(X,vecdim) Devuelve la media sobre las dimensiones especificadas en el vector.vecdim La función calcula los medios después de eliminar los valores. NaN Por ejemplo, si es una matriz, entonces es la media de todos los elementos que no son porque cada elemento de una matriz está contenido en el segmento de matriz definido por las dimensiones 1 y 2.
