How to save user input as variable I can compare?
I am trying to generate by Linear regression to get value a, then I want to get user input value b. So I can then take value a and b and plot them on a curve. But my user input is not storing values?
% Linear regression model: y ~ 1 + x1, calculate R² values for each ingredient
Mdl1=LinearModel.fit(SortedData_Cement(:,1),SortedData_Cement(:,9));
R²_Cement = Mdl1.Rsquared.Ordinary;
Mdl1=LinearModel.fit(SortedData_Blastfurn(:,2),SortedData_Blastfurn(:,9));
R²_Blastfurn = Mdl1.Rsquared.Ordinary;
% Prompt user to input a value for R² for all ingredients, accepting or rejecting value within a range. Display message to user.
exit=false;
msg=’Please enter an R² value for Cement:’;
while ~exit
data = str2double( inputdlg(msg) );
exit = (0<= data && 1>=data);
if ~exit
msg = ‘Input must be between the values 0–1. Please re-enter: ‘;
end
end
exit=false;
msg=’Please enter an R² value for Blast Furnace:’;
while ~exit
data = str2double( inputdlg(msg) );
exit = (0<= data && 1>=data);
if ~exit
msg = ‘Input must be between the values 0–1. Please re-enter: ‘;
end
end

The ‘data’ values are geing read correctly, however the second ‘data’ assignment is overwriting the first one.
Perhaps:
data(1) = str2double( inputdlg(msg) );
and:
data(2) = str2double( inputdlg(msg) );
with appropriate references to each of them in the test
