matlab中矩阵可存储的数据量

WJccn

<P>请问matalb中的矩阵最大可存储多少个数据？</P>
<P>如果超出这个范围，应该怎么办？</P>
<P>  最近在做一个模拟凝固的课题，我将我的模拟区域分割成200×200的矩阵来存储，对每个元素根据实际情况赋予了不同的数据，然后在matlab中，用不同的颜色标识出来，但是matlab提示矩阵越界，现在应该如何处理？<BR>如果超出这个范围，应该怎么办？</P>

<H2>Section 34: Product of Dimensions Is Greater Than Maximum Integer</H2><SAMP>Product of dimensions is greater than maximum integer.</SAMP>
<br><STRONG>Explanation:</STRONG><BR>You are attempting to create a full matrix with more elements than the maximum number of elements allowed in MATLAB.
<p><STRONG>Common causes:</STRONG><BR>MATLAB will attempt to create a matrix with a large number of elements, as long as that number of elements is less than the maximum number of elements allowed in a matrix. You can determine this maximum using the <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/computer.html" target="_blank" ><KBD>COMPUTER</KBD></A> function.
<p><STRONG>Solution:</STRONG><BR>If the matrix you are attempting to create has relatively few nonzero elements, you may be able to create it as a sparse matrix. You can use the <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/ref/sparse.html" target="_blank" ><KBD>SPARSE</KBD></A> function and the other sparse matrix manipulation functions to create and manage this matrix. Type
<P><PRE>help sparfun</PRE>for a list of the sparse matrix manipulation functions. Note, however, that the limitation on the maximum number of elements still exists; now it only applies to the nonzero elements of the sparse matrix. If your matrix is not sparse, however, you will need to break it into sections with a number of elements less than the maximum returned by the <KBD>COMPUTER</KBD> function.
