The question is not clear. What are "the following data"? Do you want to sort the vector?

@Muhammad SULAMAN, you ask "i am tring to find the index of all the data written in double data", so here is a list of all the indexes of all the data in your vector:

allIndexes = 1 : length(covid);

To find the index of a certain, specific value in covid, use find():

index = find(covid == 1122);

In my understanding you are trying to find an index of a particular value in double. You can use the find function. You can know more using the documentation here. Here is code for a simple example.

% Load your covid double data into "a".
a 
% Search for the value 1000
index = find(a == 1000);

What do you mean by index of all data? Do you mean that you want to load the data into your workspace ?

In the following example if I want to find data 1122, output should be its index which is 6,

Is there any way to do this?

Use the code show in this answer already:

index = find(covid == 1122)
