A = ClassName.empty A = ClassName.empty(sz1,...,szN) A = ClassName.empty(sizeVector) Description Theemptymethod creates empty arrays of a given class. For an introduction to empty arrays in MATLAB®, seeEmpty Arrays. To test if an existing array is an empty array, useisempty. ...
Size of Empty Array That Results from Deleting Elements of an Array Deleting all elements of an array results in an empty array. The size of this empty array in generated code might differ from its size in MATLAB source code. Growing Variable-Size Column Cell Array That is Initialized as...

C is normalized by the number of observations-1. If there is only one observation, it is normalized by 1. C由观察数-1归一化。 如果只有一个观察值,则将其标准化为1。 If A is a scalar, cov(A) returns 0. If A is an empty array, cov(A)returns NaN. ...
