How to store input and output arguments in a matrix form so that it can be exported to EXCEL?

Hello everyone, I have a function that gets 8 inputs and returns 8 outputs. I want to store all these arguments and intermediate results in a matrix and export them to EXCEL sheet. I got the syntax for text but could not store the arguments (numbers) in matrix.

function [a, b, c, d, e, f, g, h] = ConcWtXls (R, S, T, U, V, W, X, Y)
%main code goes on here
A{1,1} = 'Text1';
A{1,2} = 'Input';
A{1,3} = 'Intermediate Result';
A{1,4} = 'Output';

A{2,1} = 'Text2';
A(2,2) = '%.4f', R;
A(2,3) = '%.4f', iv;
A(2,4) = '%.4f', a;

%similarly the code goes on for remaining inputs and outputs
xlswrite('Samplefile.xls',A);
end

The above piece of code shows error as

Conversion to cell from char is not possible.

    Error in ConcWtXls (line 154)
    A(2,2) = '%.4f',icNaCl;

The input and output arguments are all numerical values.

This is not valid MATLAB syntax:

A(2,2) = '%.4f', R;

You will need to use curly braces to allocate to the cell array, and specify sprintf:

A{2,2} = sprintf('%.4f',R);

MATLAB is not Python, so you need to read the MATLAB documentation to know how to use MATLAB.

Thank you. I am a beginner in MATLAB and learning it day by day.
