<font face="Courier New">Dear All,<br>
<br>
I'm trying to understand the function datafit.<br>
<br>
The documentation says:<br>
<br>
</font>
<blockquote><font face="Courier New">datafit is used for fitting
data to a model. For a given function G(p,z), this function
finds the best vector of parameters p for approximating
G(p,z_i)=0 for a set of measurement vectors z_i. Vector p is
found by minimizing
G(p,z_1)'WG(p,z_1)+G(p,z_2)'WG(p,z_2)+...+G(p,z_n)'WG(p,z_n)</font><br>
</blockquote>
<font face="Courier New"><br>
I don't quite understand what is </font><font face="Courier New"><font
face="Courier New">G(p,z_1)'WG(p,z_1). Are some product signs *
missing? Shouldn't it be </font></font><font face="Courier New"><font
face="Courier New"><font face="Courier New">G(p,z_1)'*W*G(p,z_1)?</font></font>
Are these signs implied as in regular algebra notation?<br>
<br>
Thanks,<br>
