1. matlab中有一個函數iscell() 用於判斷一個數組是不是cell array
參考:MATLAB Function Reference
iscell Determine whether input is cell array Syntax tf = iscell(A) Description tf = iscell(A) returns logical 1 (true) if A is a cell array and logical 0 (false) otherwise. Examples A{1,1} = [1 4 3; 0 5 8; 7 2 9]; A{1,2} = 'Anne Smith'; A{2,1} = 3+7i; A{2,2} = -pi:pi/10:pi; iscell(A) ans = 1
2.那什么是cell array呢?
Examples This example creates a cell array that is the same size as another array, A. A = ones(2,2) A = 1 1 1 1 c = cell(size(A)) c = [] [] [] [] The next example converts an array of java.lang.String objects into a MATLAB cell array. strArray = java_array('java.lang.String', 3); strArray(1) = java.lang.String('one'); strArray(2) = java.lang.String('two'); strArray(3) = java.lang.String('three'); cellArray = cell(strArray) cellArray = 'one' 'two' 'three'
做一個類比:在java中,我們傳遞參數時特別喜歡用object定義參數類型,這樣做的好處是:可以保持接口的統一。
這里cell array:首先是一個array,其次array中的元素類型不需要統一。
