<div>Hello,</div>
<div> </div>
<div>Thank you for maintaining the web-site, it has been and continues to be very useful to me whenever I have to learn something new about TeX.</div>
<div> </div>
<div>I am writing because I have a problem with PSTricks that I do not seem to be a ble to solve, even after several hours of trying to follow the instructions on your web-site. I simply want to learn how to compile using PDFLaTeX a file containing PSTricks objects (such as psmatrix). I have tried to follow carefully the instructions in your web-site (<a href="http://tug.org/PSTricks/main.cgi?file=pdf/pdfoutput">http://tug.org/PSTricks/main.cgi?file=pdf/pdfoutput</a>) that describe how to use the package auto-pst-pdf (including enabling write18 appropriately), but to no avail. The file compiles without errors, but the psmatrix does not appear in the final pdf file.</div>

<div> </div>
<div>Please, help me out. I use the latest version of PDFLaTeX in MiKTeX. I have included the code below.</div>
<div> </div>
<div>Thank you,</div>
