Open in MATLAB Online I have a column vector Y which is 7306409x1 double. I want to find the position (indices) of a specifric number (8) in Y. I used ThemeCopy k=find(Y==8) But MATLAB gives the answer ThemeCopy k = 0×1 empty double column vector and does not show...

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 1.clear :清除内存变量和函数,把WorkSpace的变量清空; 2.clc :清除当前Matlab命令窗口的内容,注意clc不清楚变量。一般在编写m文件的时候,不是函数...
Let us see an example related to matlab find values in array, as we know find values in array is used for find indices and values of nonzero elements in the given array. So in this example, we take a number in the range of 1 to 30 with the difference of 2, and these elements ta...
这用了俩函数,一个diff一个find,diff呢是用来计算向量元素之间的差异或数组中相邻元素之间差值的,而find呢是在一个数组里面找到对应满足条件的函数 这下听懂了也听不懂了,说白了,咱们把一张图像的行和列都变成了一堆数组,事实上在MATLAB里面把所有读到的内容都可以当作一堆数组来进行处理(很有数学的风格,不愧是...
