copied!<p>The problem is in the <code>xlswrite</code> lines:</p> <p>From <a href="http://www.mathworks.com/help/matlab/ref/xlswrite.html" rel="nofollow"><code>xlswrite</code></a> documentation:</p> <blockquote> <p><code>xlswrite(filename,A,sheet)</code> writes to the specified worksheet.</p> </blockquote> <p>That means you are writing string 'b' to sheet 'A1' with <code>xlswrite(filename,'b','A1');</code></p> <blockquote> <p><code>xlswrite(filename,A)</code> writes array A to the first worksheet in Excel file, filename, starting at cell A1.</p> </blockquote> <p>You actually do not need to do anything to start writing at A1. Assuming b is a row vector:</p> <pre><code>xlswrite(filename,b'); </code></pre> <p>as you have written, should suffice.</p> <p>If you want to specify sheet and column you can use</p> <pre><code>xlswrite(filename,A,sheet,xlRange) </code></pre> <hr> <p><strong>Update:</strong> I cannot try this right now but I think it should work. </p> <p>You can calculate <code>a</code> and <code>b</code> for every <code>order</code> and write them to an xls file like this:</p> <pre><code>r = 1; % row number str = {'a', 'b'}; order = [1 3 5]; % The orders you want to calculate a and b with for idx = 1:size(order, 2) [b,a] = cheby2(order(idx), 20, 300/500); % I do not know about second % and third parameters, you should % check them. vals = [a; b]; % assuming they are row vectors cellName = strcat('A', r); orderName = strcat('Order ', order(idx)); xlswrite(filename, orderName, 1, cellName) r = r + 1; for jdx=1:2 cellName = strcat('A', r); xlswrite(filename, str{jdx}, 1, cellName); r = r + 1; cellName = strcat('A', r); xlswrite(filename, vals(jdx, :), 1, cellName); r = r + size(vals, 2); end end </code></pre>
