How to unstructure the structure data?

I want to find the mean of all rows in the data set .

But the data in the workspace is in the following formate.

let A be data set.

A=<54×10 struct>

where each row of A is in the following format

<1x1 struct> <1x1 struct> <1x1 struct> <1x1 struct> <1x1 struct> <1x1 struct> <1x1 struct> <1x1 struct> <1x1 struct> <1x1 struct>

How can I find the mean of each row of A.

@Noor Bano: please upload your data (in a mat file) by clicking on the paperclip button.

Your data is a struct array. Does it have only 1 field?

If you use the normal dot indexing with a struct array, that will generate a comma separated list.

You can put that between brackets to concatenate the resulting values, but you will need to use reshape to restore the original shape:

fn=websave('DATA.mat','https://www.mathworks.com/matlabcentral/answers/uploaded_files/742259/DATA.mat');
S=load(fn);npcr=S.npcr

npcr = 54×10 struct array with fields:
    npcr_score

reshape([npcr.npcr_score],size(npcr))

ans = 54×10

0.9959 0.9965 0.9963 0.9966 0.9959 0.9964 0.9963 0.9963 0.9958 0.9963 0.9960 0.9962 0.9962 0.9960 0.9966 0.9960 0.9962 0.9960 0.9962 0.9962 0.9959 0.9965 0.9963 0.9966 0.9959 0.9964 0.9963 0.9963 0.9958 0.9963 0.9960 0.9965 0.9960 0.9959 0.9966 0.9957 0.9960 0.9963 0.9960 0.9965 0.9961 0.9964 0.9961 0.9960 0.9962 0.9958 0.9961 0.9960 0.9963 0.9962 0.9961 0.9964 0.9961 0.9960 0.9962 0.9958 0.9961 0.9960 0.9963 0.9962 0.9959 0.9959 0.9958 0.9962 0.9960 0.9962 0.9958 0.9960 0.9958 0.9956 0.9960 0.9962 0.9962 0.9960 0.9966 0.9960 0.9962 0.9960 0.9962 0.9962 0.9959 0.9965 0.9963 0.9966 0.9959 0.9964 0.9963 0.9963 0.9958 0.9963 0.9960 0.9962 0.9961 0.9960 0.9963 0.9963 0.9961 0.9961 0.9962 0.9962

Thank you very much.

[Rik]

Why did you delete your comments?

[Ammy]

Sorry, I thought they are unnecessary after acceptance.

[Rik]

Why would you think that? They provide context for the question and the comments of others. In this case it also contained the data this answer is loading.

Please don't delete comments again.

[Ammy]

Sorry ,

Sure

thanks

@Rik, this happens so often that's why I (when I remember) to attach their data to my answer so that in case they delete it (which for some reasons they often do), it's still there. Perhaps you still have it, if you downloaded it, and can attach it. I always download rather than read it directly off the Mathworks server because (as we've found out here), if the user deletes it, it's no longer on the Mathworks server.

Also if it's the user's first or second post (not the case here), I also copy the question and attach it as a text file "OriginalQuestion.txt" to my Answer. And if it's their first or second question and they have flags that said they deleted their question, I just won't answer, and sometime tell them why I won't answer.
