在 Julia 中的给定数组索引处设置元素 – setindex!() 方法
setindex!()是 julia 中的一个内置函数,用于将给定数组X中的值存储在由 inds 指定的 A 的某个子集中。
句法:
setindex!(A, X, inds...)
参数:
- A:指定函数。
- X:指定数组。
- inds:指定索引。
返回:它不返回任何值。示例 1:
Python
# Julia program to illustrate
# the use of Array setindex!() method
# This function store values from an array
# X within some subset of A as
# specified by inds.
A = zeros(2, 2);
setindex !(A, [5, 10], [1, 2]);
A[[3, 4]] = [15, 20];
println(A)
Python
# Julia program to illustrate
# the use of Array setindex!() method
# This function store values from an array
# X within some subset of A as
# specified by inds.
A = ones(2, 2);
setindex !(A, [2, 4], [1, 2]);
A[[3, 4]] = [6, 8];
println(A)
输出:
示例 2:
Python
# Julia program to illustrate
# the use of Array setindex!() method
# This function store values from an array
# X within some subset of A as
# specified by inds.
A = ones(2, 2);
setindex !(A, [2, 4], [1, 2]);
A[[3, 4]] = [6, 8];
println(A)
输出:
