ismember structure?

I have a structure that consists of cell arrays that contain both doubles and strings.

results =

         full_data: {401x17 cell}
        order_data: {11x17 cell}

I'd like to create an array that is the size of full_data but only has the dates that are in order_data. How do you do this?

Thanks for your help!

Are all 11*17 values in order_data dates?

I like to use "intersect" for this, though "ismember" could do the trick similarly. I like intersect because I dont have to assume that the dates in order_data are a subset of full_data.

Lets say your dates look like this:

>> dates_full = (734953:734962)'

dates_full =

        734953
        734954
        734955
        734956
        734957
        734958
        734959
        734960
        734961
        734962

>> dates_order = [734954; 734958]

dates_order =

        734954
        734958

Create a new array to hold your results:

>> results_full = nan(size(dates_full))

results_full =

     NaN
     NaN
     NaN
     NaN
     NaN
     NaN
     NaN
     NaN
     NaN
     NaN

Fill the rows in results_full with the dates from dates_order that correspond to matching dates between dates_full and dates_order:

>> [temp,indx_full,indx_order] = intersect(dates_full,dates_order)

temp =

        734954
        734958

indx_full =

       2
       6

indx_order =

       1
       2

>> results_full(indx_full) = dates_order(indx_order)

results_full =

           NaN
        734954
           NaN
           NaN
           NaN
        734958
           NaN
           NaN
           NaN
           NaN
