<p>&lt;p data-start="0" data-end="269"&gt;Yes, &lt;strong data-start="5" data-end="53"&gt;you can run Python code directly from MATLAB&lt;/strong&gt; using its built-in support for Python. This is incredibly useful when you want to combine MATLAB&amp;rsquo;s numeric and visualization capabilities with Python&amp;rsquo;s wide range of libraries (like NumPy, Pandas, TensorFlow, etc.).&lt;/p&gt; &lt;hr data-start="271" data-end="274" /&gt; &lt;h3 data-start="276" data-end="299"&gt;? &lt;strong data-start="282" data-end="299"&gt;How It Works:&lt;/strong&gt;&lt;/h3&gt; &lt;p data-start="300" data-end="443"&gt;MATLAB includes a &lt;code data-start="318" data-end="322"&gt;py&lt;/code&gt; module that allows you to call Python functions, use Python objects, and import Python modules &amp;mdash; all from within MATLAB.&lt;/p&gt; &lt;hr data-start="445" data-end="448" /&gt; &lt;h3 data-start="450" data-end="500"&gt;???? &lt;strong data-start="457" data-end="500"&gt;Example: Using Python&amp;rsquo;s NumPy in MATLAB&lt;/strong&gt;&lt;/h3&gt; &lt;h4 data-start="502" data-end="542"&gt;????
