matlab hold on

The "hold on" command in MATLAB is used to retain the current plot while adding new plots to the same figure. It allows you to plot multiple lines or objects on the same graph without erasing the previous plot.

For example, if you have plotted a line using the "plot" command, and you want to add another line to the same plot, you can use the "hold on" command to prevent the previous plot from being erased. The syntax for using the "hold on" command is:

hold on

After executing this command, any subsequent plot commands will add to the existing plot without erasing it. To turn off the hold on mode, you can use the "hold off" command.

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。
