我只能用 wolfram mathematica 来画出了，不太了解 MATLAB ，不过函数的原理都一样，画出三个圆柱来，用函数方程组来指定圆柱范围：
d = ContourPlot3D[
z^2 == 100 - y^2 , {x, -11, 11}, {y, -11, 11}, {z, -11, 11},
RegionFunction ->
Function[{x, y, z}, And[x^2 + y^2 <= 100 , x^2 + z^2 <= 100]],
BoxRatios -> Automatic];
e = ContourPlot3D[
z^2 == 100 - x^2 , {x, -11, 11}, {y, -11, 11}, {z, -11, 11},
RegionFunction ->
Function[{x, y, z}, And[x^2 + y^2 <= 100 , y^2 + z^2 <= 100]],
BoxRatios -> Automatic];
f = ContourPlot3D[
x^2 == 100 - y^2 , {x, -11, 11}, {y, -11, 11}, {z, -11, 11},
RegionFunction ->
Function[{x, y, z}, And[z^2 + y^2 <= 100 , x^2 + z^2 <= 100]],
BoxRatios -> Automatic];
Show[d, e, f, PlotRange -> All, BoxRatios -> Automatic]
