朱莉娅 |带有示例的 checkbounds()函数

checkbounds()是 julia 中的一个内置函数，如果给定的索引值在给定数组的范围内，则用于返回 true，否则返回 false。

Syntax: checkbounds(Bool, Array, Index)

Parameters: This function accepts three parameters which are illustrated below:-

• Bool: This says that this function will return boolean values as output.
• Array: It is the given array with bounds
• Index: It is the index value which is going to be calculated either it lies in the array bounds or not.

Returns: It returns the value true if the index value lies in the array bounds else false.

以下是一些说明上述函数的代码：
示例 #1：

# Julia Program for illustration of
# checkbounds() function
  
# Initializing an array from 1 to 10
A = rand(1, 10);
  
# Initializing a index value of 5
Index = 5
  
# Calling the checkbounds() function
A = checkbounds(Bool, A, Index)
  
# Getting the value true or false
println(A)

输出：

true

示例 #2：

# Julia Program for illustration of
# checkbounds() function
  
# Initializing a range from 1 to 10
A = rand(1, 10);
  
# Initializing a index value of 15
Index = 15
  
# Calling the checkbounds() function
A = checkbounds(Bool, A, Index)
  
# Getting the value true or false
println(A)

输出：

false
