If you do need to grow an array, see if you can do it using the repmat function.

You can convert a full matrix to sparse using the sparse function.įor more information: See Converting Full Matrices into Sparse in the MATLAB "Programming and Data Types" documentation, and the sparse function reference page Sparse matrices can use less memory and may also be faster to manipulate than full matrices. Matrices with values that are mostly zero are best stored in sparse format.

After saving that portion of the data, clear the variable from memory and continue with the data generation. If your program generates very large amounts of data, consider writing the data to disk periodically. Use clear to do this.Ĭonserving Memory with Large Amounts of Data

If you use pack and there is still not enough free memory to proceed, you probably need to remove some of the variables you no are longer using from memory. If you get the Out of Memory message from MATLAB, the pack function may be able to compress some of your data in memory, thus freeing up larger contiguous blocks.įor more information: See Ways to Conserve Memory in the MATLAB "Programming and Data Types" documentation When memory is fragmented, there may be plenty of free space, but not enough contiguous memory to store a new large variable. Since MATLAB uses a heap method of memory management, extended MATLAB sessions may cause memory to become fragmented. Reload a data file saved with the save function.Įxit MATLAB and return all allocated memory to the system. Save existing variables to disk, and then reload them contiguously. Several functions that are useful in managing memory are listed below.
