朱莉娅 |带有示例的 checkindex()函数

checkindex()是 julia 中的内置函数，如果给定的索引值在范围内，则用于返回 true，否则返回 false。

Syntax: checkindex(Bool, Range, Index)

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

• Bool: This says that this function will return boolean values as output.
• Range: It is the specified range.
• Index: It is the index value which are going to be calculated either it lies in the range or not.

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

以下是一些说明上述函数的代码：
示例 #1：

# Julia Program for illustration of
# checkindex() function
  
# Initializing a range value from 1 to 10
Range = 1:10
  
# Initializing a index value of 5
Index = 5
  
# Calling the checkindex() function
A = checkindex(Bool, Range, Index)
  
# Getting the value true or false
println(A)

输出：

true

示例 #2：

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

输出：

false
