In this video, you’ll learn how to take output from a function or multiple functions to create a vector. By creating a vector from a single output or multiple outputs, you can perform operations and functions on single or select elements using array indexing. Array indexing helps you efficie...
creating a vector from a(:) : b(:) , but one for each index without using loops.-loop just make pull out as many computations as you can which it looks like you've done already.
v = [ 1; 2; 3; 4; 5; 6]; % creating a column vector of 6 elementsv(3) 1. 执行上述语句,返回下述结果: ans = 3 1. 当引用一个冒号,一个向量,其例如为v(:),该载体上的所有组件的被列出。 例如: v = [ 1; 2; 3; 4; 5; 6]; % creating a column vector of 6 elementsv(:) ...
MATLAB Online で開くlets say that you want to create a vector length "m" and want to go up to "n" and then be constant and then decrease:テーマコピーfunctiony=increasedecreasefun(m,n)A=n*ones(1,m);fori=1:n-1A(i)=i;A(m-i+1)=i;end...
Trial>> v = [ 1; 2; 3; 4; 5; 6]; % creating a column vector of 6 elements v(:) ans = 1 2 3 4 5 6 Shell MATLAB可从向量中选择一系列元素。 例如,创建一个9个元素的行向量rv,然后通过rv(3:7)引用3到7元素,然后引用来向一个新创建的sub_rv向量赋值。如下代码所示 - ...
Use a to modify properties of the areas after creating them. For a list of properties, see Area Properties. exampleExamples collapse all Create Area Plot with One Curve Copy Code Copy Command Create a vector of four values. Display the values in an area plot. Get y = [1 5 6 3]; ...
Given N, simulate 1e8 N-sided dice rolls by creating a vector of 1e8 uniformly distributed random integers. Return the difference between the mean of this vector and the mean of integers from 1 to N. 验证大数定律。给定N,返回1到N的均值(也就是N+1除以2)和1-N的随机数重复出现1e8次的...
Modify the legend appearance by setting the Legend property. When creating a legend, you can use name-value pairs in the legend command to set properties. You can also use the Legend object to set properties after the legend is created. ...
Drawing a 3D line graph is similar to drawing a 2D line graph, but it has one more z-axis in the vertical direction than the 2D graph, and one more vector needs to be defined when drawing, and the function used has changed from plot to plot3. ...
