函數(shù)簡(jiǎn)介函數(shù)功能 使用箭頭繪制矢量圖。例如,該函數(shù)可用于繪制梯度圖。 語法格式 quiver(x,y,u,v) 該函數(shù)使用箭頭來直觀的顯示矢量場(chǎng)。該調(diào)用格式表示通過在(x, y)指定的位置繪制小箭頭來表示以該點(diǎn)為起點(diǎn)的向量(u,v)。 x、y、u、v的行數(shù)、列數(shù)必須對(duì)應(yīng)相等。即x、y、u、v必須是同型矩陣。 需要注意的是,如果x、y不是矩陣,MATLAB會(huì)調(diào)用meshgrid函數(shù)將其擴(kuò)展。然后再調(diào)用quiver函數(shù)。在這種情況下,x中元素的個(gè)數(shù)必須等于u、v的
