MATLAB combines a desktop environment tuned for iterative analysis and design processes with a programming language that expresses matrix and array mathematics directly. It includes the Live Editor for creating scripts that combine code, output, and formatted text in an executable notebook. Professionally...
matlab里有一个函数isprime,是用来判断一个数a是不是素数。x=isprime(a),如果a是素数则x等于1,否则等于0;你要是求素数的话用一个for语句就行了,给你写了个m文件,求1到n之间所有素数。实现代码如下:isprime(int i) %是用来判断一个数是不是素数 { x=i;if (x==1||x==2)y='素...
进if循环是里面有字符数据,不进if里面无数据,自然会造成这个的问题。可以使用cell单元,即将源代码改为 for i=1:1:n;if dat1{i}=='DEPTH';a{ai}=i;b{ai}=1;break;end end a = cell2mat(a);b = cell2mat(b);a = isempty(a);b = isempty(b);就跟你要输出的结果一样了。

a{i}(j)中i表示访问的是第i个元胞,而j表示第i个元胞中的第j个数
列出矩阵的a的第i个元素到第j个元素,如a=[1 2 3 4 5 6 7 8 9;2 3 4 5 6 7 7 8 9];则 a(1:4)= 1 2 2 3,其中读取顺序为matlab把矩阵按列排放,a'ans = 1 2 2 3 3 4 4 5 5 6 6 7 7 7 8 8 9 9 所以它是按行读的 ...
