Suppose I have a 300 by 300 matrix, containg the values from 0 to 200. For each column, I want to find the position of the first element which is greater than 50. how do I do it. I have tried to write a code but can't do it any fu...
MATLAB是“matrix laboratory”的缩写形式。MATLAB® 主要用于处理整个的矩阵和数组,而其他编程语言大多逐个处理数值。 所有MATLAB 变量都是多维数组,与数据类型无关。矩阵是指通常用来进行线性代数运算的二维数组。 数组创建 [外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-Bqb7fvFg-165882387...
Let see one more example of matlab find values in array function. In this example, we create a matrix, and then we see how matlab finds values in array works. So first, we started with creating a 2–by–2 matrix that contains random integer numbers among 1 to 4. Next, we used the ...
nTime = size(ErrKarray,3); % number of time steps in each simulation ErrKPos = zeros(1, nTime); % position error of unconstrained Kalman filter ErrKVel = ErrKPos; % velocity error of unconstrained Kalman filter ErrKCPos = ErrKPos; % position error of constrained Kalman filter ErrKCV...
Find the minimum value of Rosenbrock's function when there are both a linear inequality constraint and a linear equality constraint. Set the objective function fun to be Rosenbrock's function. Get fun = @(x)100*(x(2)-x(1)^2)^2 + (1-x(1))^2; Find the minimum value starting ...
调整'DegreeOfSmoothing'以适应热成像图像的范围。显示过滤后的图像。 smoothValue = 0.01*diff(range).^2; J = imguidedfilter(I,'DegreeOfSmoothing',smoothValue); figure imshow(J,[]) colormap(gca,hot) title('Guided filtered image') 确定用于细分的阈值。图像具有3个不同的区域-人,热的物体和...
The recommended value is'pixels', because most MATLAB app building functionality measures distances in pixels. You can create a table that rescales based on the size of the parent container by parenting the table to a grid layout manager created using theuigridlayoutfunction. For more information...
function RPM=RelativePositionMatrix(x,k) % 计算相对位置矩阵(Relative Position Matrix, RPM) % 输入:x,一维时间序列 % k,分段聚合近似(PAA)的缩减因子 % 输出:RPM,相对位置矩阵 mu = mean(x); delta = sqrt(var(x)); z = (x-mu)/delta; % PAA N = length(x); m = ceil(N/k); if ceil...

text(x,y,'text-at-x,y') displays text at position (x, y) in the graphics window where x and y are measured in the units of the current plotting axes. There may be one point or many at which text is placed depending on whether or not x and y are vectors. gtext('text') allows...
