Question

我想增加箭袋中的箭头大小。显然，matlab中没有这样的属性。我尝试在quiver.m

中更改以下内容

% Arrow head parameters
%alpha = 0.33; % Size of arrow head relative to the length of the vector
%beta = 0.33;  % Width of the base of the arrow head relative to the length
alpha = 100000050.5; beta = 0.5;
autoscale = 0; % Autoscale if ~= 0 then scale by this.
plotarrows = 1; % Plot arrows

但是没有效果。请使用以下示例作为上述曲线之一。
