plotting correlation matrix using python
<p>I want to plot the correlation matrix using python. I have tried with the following script</p>

<pre><code>  corr_matrix=np.corrcoef(vector)
  imshow(corr_matrix, interpolation='bilinear')
  colorbar()
  show()
</code></pre>

<p>The dimension of the matrix is 2500X2500. The above code produces a matrix of full of dots. But I want smooth surface. How do I get that.</p>

<p>Best
