Hello. I hope you are doing Well. I have import Data from website. I need to convert the Char array in Table with Values in Each Column
For Example In the following data I have 2x2 cell. The first Cell Predicted Class is the Column name and Airplane is the Value.
The second Cell will be Column name Maximum Amp and Time Value corresponding to there Values.
The C1 is the first Class and C2 is the Second Class so it should be in loop to save the data for multiple classes.
Can anybody help me with that.

Ran in:
y=load('Data.mat').Datawebsite
y = 2×2 cell array
{'C1 Predicted Class: Airplane' } {' Maximum Amp: [-14.5052] Time (s): 2.5988 '} {'C2 Predicted Class: AirplaneCombat'} {' Maximum Amp: [-30.1052] Time (s): 4.853 ' }
It's not clear how you want to store this data in Table. What is supposed to be the format of the Table? Direct conversion column wise?
out=cell2table(y)
out = 2×2 table
y1 y2 ______________________________________ ______________________________________________ {'C1 Predicted Class: Airplane' } {' Maximum Amp: [-14.5052] Time (s): 2.5988 '} {'C2 Predicted Class: AirplaneCombat'} {' Maximum Amp: [-30.1052] Time (s): 4.853 ' }
Please give a sample output.

You can use regexp to extract the data.
load('Data.mat')
[m,n] = size(Datawebsite) ;
predictedClass = cell(m,1) ;
maximumAmp = zeros(m,1) ;
time = zeros(m,1) ;
expression1 = ':\s*(\w+)';
expression2 = '-?\d+\.\d+';
for i = 1:m
string1 = Datawebsite{i,1} ;
tokens = regexp(string1,expression1,'tokens');
predictedClass{i} = tokens{1}{1};
string2 = Datawebsite{i,2} ;
tokens = regexp(string2,expression2,'match');
maximumAmp(i) = str2double(tokens{1});
time(i) = str2double(tokens{2});
end
T = table(predictedClass,maximumAmp,time)

You have the code for your asked case...you can extends the same to your case. It is straight forward.
