help writing a script which outputs the daily percentage of positive COVID-19 cases

Hello all,

I'm trying to write a script which gives the daily percentage of positive COVID-19 cases for Oregon. So far I have

%Analysis of daily percentage of positive COVID-19 test in the state of Oregon
clc 
clear all
close all

%load data from https://covidtracking.com/data/state/oregon
api='https://covidtracking.com/api/v1/states/OR/daily.json'
data=webread(api)

This gives a 76x1 cell with all 1x1 structres. I would like to get the data from these structers so I can use the variables to produce a best fit using either one of the two equations 1/x/a/sqrt(2*pi)*exp(-(log(x)-b)^2/2/a^2) where a,b are variables.

It looks like you edited the question and replaced it by your new question. Why did you do that? You made the answer by Ameer completely useless now.

In response to your email: the preferred way is to leave a question as it was, instead of replacing it. Asking multiple questions is fine.

If you still have a copy of the original question text I don't see any issues with restoring it yourself. Otherwise you can leave it for a site admin to revert, but they are busy, so that can take up to several weeks to do.

This shows how to extract data from a particular field

api='https://covidtracking.com/api/v1/states/OR/daily.json';
data=webread(api);

dataTotal = cellfun(@(x) x.('total'), data);
dataPositive = cellfun(@(x) x.('positive'), data);
dataNegative = cellfun(@(x) x.('negative'), data);
