Mathematics, MATLAB Version 7.0.4 (R14SP2) Release Notes

Mathematics, MATLAB Version 7.0.4 (R14SP2)

This version introduces the following new features and changes:

• New Vendor BLAS Used for Linear Algebra in MATLAB

• max and min on Complex Integers Not Supported

New Vendor BLAS Used for Linear Algebra in MATLAB

MATLAB uses Basic Linear Algebra Subprograms (BLAS) for its vector inner product, matrix-vector product, matrix-matrix product, and triangular solvers in \. MATLAB also uses BLAS behind its core numerical linear algebra routines from Linear Algebra Package (LAPACK), which are used in functions like chol, lu, qr, and within the linear system solver \.

Starting in this release

• On Macintosh, MATLAB now uses the Accelerate framework.

• On 64-bit Linux, MATLAB uses Intel^® Math Kernel Library (MKL) 7.0.1 on Intel chips, and AMD Core Math Library (ACML) 2.0 on AMD chips.

max and min on Complex Integers Not Supported

Using the max and min functions on complex integer inputs (as shown in the example below) is no longer supported. This operation had been supported from release R11 through R14SP1, but now returns an error.

max(int8([3-4i 3+4i]))

Compatibility Considerations

Any code that calls max or min on complex integers should be removed from your program files.
