具体如下：“calLength.m”的内容是：function segs=calLength(P1,P2)segs.length=[];segs.index_x =[];segs.index_y =[];segs.index =[];P1_x = P1(1);P1_y = P1(2);P2_x = P2(1);P2_y = P2(2);xmin = min(P1_x,P2_x);ymin = min(P1_
The MatLab functions, sub2ind() and ind2sub(), translate between two “subscripts”, i and j, and a vector “index”, k, such that A(i,j)=A(k). The reshape() function can reorganize any N× M matrix into a K× L matrix, as long as NM = KL. Thus, for example, a 4 × 4...
,因此前面的阶乘函数可以改成递式的写法: function output = fact(n) % FACT Calculate factorial of a given positive integerrecursively. if n == 1, % Terminating condition output = 1; return; end output = n*fact(n-1); 在写一个递函数时,一定要包含...

sign(x):符号函数 (Signum function)。 当x<0时,sign(x)=-1; 当x=0时,sign(x)=0; 当x>0时,sign(x)=1。 > 小整理:MATLAB常用的三角函数 sin(x):正弦函数 cos(x):馀弦函数 tan(x):正切函数 asin(x):反正弦函数 acos(x):反馀弦函数 ...
Create a matrix A and return the maximum value of each row in the matrix M. Use the "linear" option to also return the linear indices I such that M = A(I). Get A = [1 2 3; 4 5 6] A = 2×3 1 2 3 4 5 6 Get [M,I] = max(A,[],2,"linear") M = 2×1 ...
This MATLAB function returns a vector with the local maxima (peaks) of the input signal vector, y.
最大、最小函数 max([a,b,c,...]) 求最大数 min([a,b,c,..]) 求最小数 符号函数 sign(x) 5 自定义函数-调用时:“[返回值列]=M文件名(参数列)” function 返回变量=函数名(输入变量) 注释说明语句段(此部分可有可无) 函数体语句
