Plot data from array Hi! I'm having some difficulties to plot some date the way i want to. I hope someone can help. I made a speaker recognition system using MFCC and GMM, and I made some test. Now I want to plot the results. I made some simulations with 1 to 24 MFCC coefficient...
例如,假设你的Excel文件名为data.xlsx,A列是x轴数据,B列是y轴数据,你可以这样操作:1. 使用importdata函数导入Excel文件:data = importdata('data.xlsx');2. 提取A列和B列 在使用MATLAB进行绘图时,如果遇到错误提示“错误使用 plot”,通常表明输入的数据存在不匹配的情况。例如,当你尝试执行 plot(x,F) 这个命...
What data do you want on the x-axis? What data on the y-axis? What does your data represent? "plot the data" is pretty generic, so more information would help others answer your question. From your question it looks like you are trying to use the plotSpread function from the MATLAB ...
usereadmatrixto load the data from the txt file then usereshapeto convert your vector of 10,000 values to an 2D array of size 100 x 100 (pay attention how you want the data be reorganized in row or column directions) then you can plot using one the many available functions of 3D plot...
A convenient way to plot data from a table is to pass the table to the plot3 function and specify the variables to plot. Create vectors x, y, and t, and put the vectors in a table. Then display the first three rows of the table. Get t = (0:pi/20:10*pi)'; x = sin(t)...
if iteration == 1 || ~hasdata(mbq) [~,scoresValidation] = modelPredictions(net,mbqValidation,classes); lossValidation = crossentropy(scoresValidation,TValidation); % Update plot. recordMetrics(monitor,iteration,ValidationLoss=lossValidation); end monitor.Progress = 100*iteration/numIterati...
The examples provided in the documentation of following MATLAB Script function might use functions that are not available in MATLAB Script (e.g., plot, figure, subplot, wvtool, dfilt, fvtool, fdesig…
双击示波器后单击菜单栏parameters,点开history选项,将Save data to workspace勾上,Format选择Array,Variable name即你输入至工作空间的矩阵名称,比如a。在这之后运行一次仿真,那么你就可以在MATLAB的工作空间里看到你示波器输出曲线的矩阵a。然后根据这个矩阵a就可以绘制图形。curve=plot(a(:,1),a(:,2 ...
matlab中subplot是在各个分块位置创建坐标区的意思。例如:在一个图窗中,创建带有两个堆叠子图的图窗。在每个子图上绘制一条正弦波。subplot(2,1,1);x = linspace(0,10);y1 = sin(x);plot(x,y1)subplot(2,1,2); y2 = sin(5*x);plot(x,y2)运行结果 1、subplot(1,2,1):一个FI ...
a = np.array([[1,2,3,4],[5,6,7,8]]) print('数组维数: ', a.ndim) #返回int,表示数组的维数 print('数组尺寸: ', a.shape) #返回tuple,表示数组的尺寸(n,m) print('元素总数: ', a.size) #返回int,表示数组的元素总数 print('元素类型: ', a.dtype) #返回data-type,表示数组中元素...
