What’s new R2023a

R2023a has landed with some new products and some exciting major updates. 

C2000 Microcontroller Blockset


MATLAB Test™ provides tools for developing, executing, measuring, and managing dynamic tests of MATLAB® code, including deployed applications and user-authored toolboxes. You can use the project-based quality dashboard to raise the visibility of code readiness to an intuitive summary level. The dashboard is an interactive, graphical summary of code quality metrics with clickable details for code analysis, code coverage, test results, and requirements.

MATLAB Test manager helps you organize and manage tests and results in your project by enabling you to group, save, and run custom test suites at scale. You can identify untested code paths using industry-standard code coverage metrics, such as condition, decision, and modified condition/decision coverage (MC/DC). Persistent test results enable you to optimize productivity by only rerunning select tests to verify code edits. You can reduce test execution time of large test suites by leveraging dependency-based test selection, by running tests in parallel, or within continuous integration systems.

You can verify the expected behavior of artifacts created with MATLAB Coder™ and MATLAB Compiler SDK™ using functional equivalence testing techniques. MATLAB Test enables you to meet specifications in regulated applications by tracing requirements (with Requirements Toolbox™). Support for industry standards is available with the IEC Certification Kit (for ISO® 26262, IEC 61508, and IEC 62304).
