How do I verify the integrity of a download from MathWorks.com?

I have downloaded the ISO image/ installer/ update packages for installation and I want to check the file's checksum to verify the integrity of the file. How can I get the file's checksum?

The checksum is a sequence of numbers and letters that you can use to check that your copy of a downloaded file is identical to the original. If the checksum does not match what is displayed on the website, the file may have been corrupted or tampered with and a new version should be downloaded.

When downloading a file from https://www.mathworks.com/downloads/, for R2024a and newer the SHA256 checksum is displayed, for R2023b and older the MD5 checksum is displayed.

The following command-line utilities can be used to calculate the checksum of the given file. Change the file name (in italics) as applicable.

For R2024a and newer downloads:

• Windows: Open Command Prompt and run the following command. Make sure to put "SHA256" in capital letters. 

  CertUtil -hashfile matlab_R2024a_Windows.exe SHA256

• Linux: Open a terminal and run the following command.

  sha256sum matlab_R2024a_Linux.zip

• macOS: Open a Terminal and run the following command.

  shasum -a 256 matlab_R2024a_macOSAppleSilicon.dmg

For R2023b and older downloads:

• Windows: Open Command Prompt and run the following command. Make sure to put "MD5" in capital letters.

  CertUtil -hashfile R2018b_win64_dvd1.iso MD5

• Linux: Open a terminal and run the following command.

  md5sum R2018b_glanxa64_dvd1.iso

• macOS: Open a Terminal and run the following command.

  md5sum matlab_R2018b_maci64.dmg

It may take a few minutes for the commands to calculate the checksum.

Only a License Administrator can download the ISO and view the hash of them on MathWorks.com.
