Matlab加载整个文件，但逐段显示和绘图 [英] Matlab load entire file but show and plot segment by segment

问题描述

是否可以加载文件并逐段显示/绘制?我想知道是否有可能，任何人都可以指导我.我设法做到了

Possible to load file and show/plot it segment by segment? i want to know if it is possible and anyone can guide me along. i have manage to do this matlab peak value (found the peak but want to know the value) and now i'm gonna add on to it so i hope you guys don't put my questions on hold/downvoted me. i really need help

示例:

数据大小:10000

Data size: 10000

意图:要加载整个文件，但在1时刻，图仅显示1000个数据，而不显示并绘制整个10000个数据.

Intention: To load the entire file, but at 1 time the fig only show 1000 data instead of showing and plotting the entire 10000 data.

说明: 当我按某些命令时，它将绘制前1000个数据.然后按Enter或某些命令，它将绘制1001-2000等等.

Explanation: When i press some command it will plot the first 1000 data. then i press enter or some command it will plot 1001 - 2000 and so forth..

我有Google，但似乎找不到任何类似的问题

I have google but don't seems to find any similar questions

需要建议.

推荐答案

也许这个例子会有所帮助:

Maybe this example will be helpful:

data = 1:10000;
rows = reshape(data, 1000, numel(data)/1000)';

for ri = 1:size(rows,1)
    figure, plot(rows(ri,:));
    pause;
end

它将数据矢量重塑为10 x 1000的矩阵，以便行包含连续的1000个数据值.然后，只需遍历行并绘制它们以等待按键.

It reshapes data vector into matrix 10 x 1000, so that rows contain consecutive 1000 data values. Then just loop over rows and plot them waiting for keypress.
