To check if a variable is an array in Julia, you can use the isa
function. This function returns true
if the variable is an array, and false
otherwise. Here are some examples:
Check if Variable is Array in Julia Example
# Define some variables x = [1, 2, 3] y = "hello" z = (1, 2, 3) # Check if the variables are arrays println(isa(x, Array)) # Output: true println(isa(y, Array)) # Output: false println(isa(z, Array)) # Output: false
In this example, we define three variables: x
, y
, and z
. x
is an array of integers, y
is a string, and z
is a tuple. Then, we use the isa
function to check if each variable is an array. Since x
is an array, isa(x, Array)
returns true
. However, since y
and z
are not arrays, isa(y, Array)
and isa(z, Array)
both return false
.
