区分vector与matrix:vector指向量,matrix指矩阵,而array则是两者的统称。 ,和空格用来间隔列column,;用来间隔行row a = [1 2 3]; %这是一个行向量 b = [4, 5, 6]; %这也是一个行向量 c = [7; 8; 9]; %这是一个列向量 1. 2. 3. 向量乘法 行向量乘列向量结果是一个数,而列向量乘行向量...
The first parameter (here, 1) is the maximum random integer (the minimum is 1). Since the max is the same as the min, this randi command will only produce 1's. The second and third parameters give the size of the array you want. So I suspect you really want something like ...
C = max(A,B) returns an array the same size as A and B with the largest elements taken from A or B. C = max(A,[],dim) returns the largest elements along the dimension of A specified by scalar dim. For example, max(A,[],1) produces the maximum values along the first dimension...
max(A,2)矩阵和2进行比较,min(A,[ ],2)行内进行比较; max和min用法相同;min(A,[ ],1)等价于min(A) 11、常见运算:注意乘号使用,我们一般使用的时.*。注意点乘和点除与乘和除的区别 12、关系运算符 13、逻辑运算: & 逻辑与; | 逻辑或; ~ 逻辑非; xor 异或; any 有非零元则为真; all...
matlab gpu清除内存,本篇汇总了Matlab中常用的命令,包括:会话管理,系统命令,输入输出,矩阵运算,绘图等,并在后面附上实例说明。---常用命令语句---管理会话的命令命令目的/作用clc清除命令窗口。clear从内存
在matlab中length函数和size函数都是用来显示矩阵长度的函数。二者的区别为: * length函数返回的是矩阵中行数和列数的较大值 * size函数返回的是矩阵中的行数和列数。且返回的第一个值代表的是行数,第二个值代表的是列数 1、对于length函数: * 行数较大时: ...
Index in position 2 exceeds array bounds (must not exceed 4). 不过,您可以在赋值语句左侧指定当前维外部的元素。数组大小会增大以便容纳新元素。 A(4,5) = 17 A = 4×5 1 2 3 4 0 5 6 7 8 0 9 10 11 12 0 13 14 15 16 17
