Add interpolated data at a specific location in the main array.

Hello,
I am working with an array which has a size of 603x1. However, there is data that is missing at two locations in the array. I have used the interp1 function to determine missing data and have it stored in a matrix. The location where the data is missing has 25 and 14 interpolated points respectively. I want to add the interpolated data into the main array at the specific locations, which are between the elements 28 and 29, and 186 and 187 respectively, such that the new array has a size of 642x1. I have attached the two variables with this question for reference. How can this be done?
Kind regards,
Harjot

This way?
array_new=[array_data(1:28),int_data,array_data(29:end)]

a =tlv_lis_alt;
input = interpol_alt;
idx = [29;187];
k = numel(a);
b = ones(k,1);
[m,n] = size(input);
lo = ~isnan(input);
ct = sum(lo);
b(idx) = ct + 1;
out = nan(sum([k;ct(:)]),1);
out(cumsum(b)) = a;
out(isnan(out)) = input(lo);
