Could you help me in creating a string array with strings containing characters and numbers in a sorted manner

Eg:

I want to create a string array with strings {"Analysis_1", "Analysis_2", "Analysis_3", "Analysis_4", ......, "Analysis_n"}

The values of 'n' should be defined in way that it can be varied by the user.

在 MATLAB Online 中打开

n = 5;
S = "Analysis_" + (1:n)
S = 1×5 string array
    "Analysis_1"    "Analysis_2"    "Analysis_3"    "Analysis_4"    "Analysis_5"

You can also use implicit expansion to make an array if you so desired.

fruits = ["apple"; "banana"; "cherry"]
fruits = 3×1 string array
    "apple"
    "banana"
    "cherry"
quantity = 1:4;
market = fruits + "_" + quantity
market = 3×4 string array
    "apple_1"     "apple_2"     "apple_3"     "apple_4" 
    "banana_1"    "banana_2"    "banana_3"    "banana_4"
    "cherry_1"    "cherry_2"    "cherry_3"    "cherry_4"
