Use this matrix operation to transform, inspect, serialize, or decompose a rectangular numeric array with known dimensions and mathematical assumptions.

Matrix

Non-empty rectangular matrix.

Direction

Rotation direction; clockwise is the default.

Rotate a matrix by 90 degrees clockwise or counterclockwise. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Rotated matrix

Matrix rotated by 90 degrees with transposed dimensions.

• Dimension compatibility, numeric conditioning, symmetry, positive definiteness, rank, scaling, tolerance, and floating-point precision affect matrix results. Serialization formats may lose types or precision.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check dimensions and prerequisites, compute reconstruction or residual error for decompositions, and compare ill-conditioned cases with a trusted numerical library.
