Matlab内存不足。使用pdistmex

Question

我有一个矩阵M，大小为（262322x4）。在运行knn插补时：

M=csvread("C:\Users\Hello\Desktop\DATA\B.csv",1,0);
B = transpose(M);
A = knnimpute(B,1);
C=transpose(A);

我收到以下错误：

>>knn_imputation
Error using pdistmex
Out of memory. Type HELP MEMORY for your options.

Error in pdist (line 264)
Y = pdistmex(X',dist,additionalArg);

Error in knnimpute (line 162)
distances = pdist(dataNoNans',metric,distargs{:});

Error in knn_imputation (line 4)
A = (knnimpute(B,1));

此错误是由于内存限制还是其他原因引起的？

（注意：内存大小：8GB）
