M contour

基本解釋

All three basins are enclosed by the 1900 m depth contour .
三個(gè)海盆都被1900米的等深線所圈閉。
And, I'm going to take the same two examples as there to start with so that we see the relation between the graph and the contour plots.
我將擧出兩個(gè)相同例子,這樣我們就能看到圖像與等高線圖的關(guān)系。
So, say I have a function of two variables, x and y then maybe it has some contour plot And, I'm saying if I take the gradient of a function at this point So, I will have a vector.
這是一個(gè)關(guān)於兩個(gè)變量x，y的函數(shù),假設(shè)它有一些等值線,如果我在這點(diǎn)処,計(jì)算函數(shù)的梯度）,也就得到了一個(gè)曏量。
