 <p>You can find the value of the exponent using <code>log10</code>:</p> <pre><code>testVector = [3.5688e+10 3.1110e+10 5.2349e+10]; lowExp = min(floor(log10(testVector))); eVal = 10^lowExp; </code></pre> <p>Result:</p> <pre><code>eVal = 1.0000e+10 </code></pre> <p>Then you'll need to divide your original vector by <code>eVal</code>:</p> <pre><code>newTestV = testVector/eVal newTestV = 3.5688 3.1110 5.2349 </code></pre>
