matlab hold on

The "hold on" command in MATLAB is used to retain the current plot and add subsequent plots to it.

For example, if you plot a graph using the "plot" command, and then use the "hold on" command before plotting the second graph, the second graph will be plotted on the same figure as the first graph.

Here is an example code snippet:

x = 0:0.1:2*pi;
y1 = sin(x);
y2 = cos(x);

plot(x, y1)
hold on
plot(x, y2)

In this example, the "hold on" command is used to keep the first plot (sin(x)) on the figure, and add the second plot (cos(x)) to it. If "hold on" was not used, the second plot would overwrite the first one.

MATLAB hold on

The "hold on" command in MATLAB is used to retain the current plot and add new plots to the same figure.

For example, if you have plotted a graph using the "plot" command and you want to add another plot to the same graph, you can use the "hold on" command before plotting the new data.

Here is an example:

x = 0:0.1:2*pi;
y1 = sin(x);
y2 = cos(x);

plot(x, y1);
hold on;
plot(x, y2);

In this example, the first plot command will plot the sine function and the "hold on" command will retain the current plot. The second plot command will plot the cosine function on the same graph as the sine function.

Without the "hold on" command, the second plot command would create a new figure and plot the cosine function on a separate graph.

Note that you can turn off the "hold on" behavior using the "hold off" command.

matlab hold on是什么意思

"hold on" 是 MATLAB 中的一个命令，它可以让图形窗口保持打开状态，以便在同一张图上绘制多个图形。当使用 "hold on" 命令后，每次绘制新的图形时，它们将被添加到同一张图上，而不是覆盖原来的图形。
