| 4 | % Description | ||
| 5 | % D = DIST2(X, C) takes two matrices of vectors and calculates the | ||
| 6 | % squared Euclidean distance between them. Both matrices must be of | ||
| 7 | % the same column dimension. If X has M rows and N columns, and C has | ||
| 8 | % L rows and N columns, then the result has M rows and L columns. The | ||
| 9 | % I, Jth entry is the squared distance from the Ith row of X to the | ||
| 10 | % Jth row of C. | ||
