matlab 中 A(a:b:c)是什么意思
y1= -0.002:0.0004:0.002
y0=( -0.036:0.001:0.036)'*ones(1,73);
z0=ones(73,1)*(-0.036:0.001:0.036);
y1,y0,z0 分别是什么, 语句是什么意思

y1= -0.002:0.0004:0.002 表示 y1 是一个向量,起始值是 -0.002,元素的增量是 0.0004,最后一个元素是 0.002
A(a:b:c) 就是取出 A 中索引值为 [a, a+b, a+2b, a+3b, ...., c] 的元素,最后一个值 c 是否能取到,取决于 c - a 是否正好是 b的整数倍
