What's New in Mathematica 12.2
Mathematica 12.2 adds 228 new functions, expanding the Wolfram Language's functionality in biomolecular sequence operations, PDE modeling, spatial statistics, remote batch job evaluation and more.
Stephen Wolframs Blog Entry announcing Version 12.2
- Represent a biological sequence such as DNA with
BioSequenceand perform operations on it with functionsBioSequenceTranscribe,BioSequenceComplement, etc. - New PDE modeling framework for solving a wide variety of partial differential equations both symbolically and numerically
- Analyze spatial data and work with point processes with new spatial statistics functions such as
SpatialPointData,RandomPointConfiguration,MeanPointDensity,PointCountDistributionand more - Submit batch jobs for asynchronous evaluation on external computation providers with
RemoteBatchSubmitandRemoteBatchMapSubmit - Use
EncloseandConfirmto write code with more robust error handling CheckArgumentsandArgumentsOptionshelp check for valid positional and optional arguments in function definitions- New
x|->fsyntax for defining pure functions with named variables - Use
ApplyTo (//=)to apply a function to a variable and update its value - Conveniently select dates from date intervals or lists with
DateSelect - Improve code debugging and tuning with new
EchoEvaluation,EchoLabelandEchoTimingfunctions - New theories and properties added to
AxiomaticTheory - Solve general convex optimization problems with
ConvexOptimization - Find solutions to robust optimization problems with
RobustConvexOptimizationand to parametric convex optimization problems withParametricConvexOptimization - Test for various function properties with
FunctionInjective,FunctionSign,FunctionContinuous, etc. - Improved support for elliptic functions, including addition of the JacobiEpsilon and JacobiZN (Jacobi zeta) functions
- Mathematical Lamé functions
LameS,LameC,LameSPrime,LameCPrime,LameEigenvalueAandLameEigenvalueBfor solving boundary value problems for Laplace's equation in ellipsoidal and spheroconal coordinates - Create radar plots with
RadialAxisPlot ParallelAxisPlotcreates parallel coordinate plots- Represent 2D geographic regions with
GeoPolygon, a new GeoGraphics primitive - Artistically fill 2D graphics primitives with
LinearGradientFilling,RadialGradientFillingandConicGradientFilling - Test convexity and compute the convex hull of any region with
ConvexRegionQandConvexHullRegion - Check if a set of points is positively oriented, negatively oriented, collinear or coplanar with
PositivelyOrientedPoints,NegativelyOrientedPoints,CollinearPointsandCoplanarPoints, respectively - Greatly improved support for video computation, with new functions such as
VideoGenerator,VideoIntervals,VideoDelete,VideoMap,VideoMapTimeSeriesand more - New
AnimatedImageobject to represent animated GIF, PNG, etc. - Use
FaceRecognizeto find and recognize faces in an image using machine learning - Support for several new neural network layer types, including
FunctionLayer,CompiledLayer,NetArrayLayerandRandomArrayLayer - Several new methods for
DimensionReductionandDimensionReducehave been added, including t-SNE, principal component analysis and latent semantic analysis - Support for compression and archival formats 7z, ISO, RAR and ZSTD
- Represent public-key security certificates with
SecurityCertificateand import them from common variants of the PEM file format - Significant improvement to PDF import
- Improved Import with support for URLs, updates to
FileFormatand addition ofFileFormatQand more - Create on-demand license entitlements to run standalone Wolfram Engine kernels on a pay-as-you-go basis with
CreateLicenseEntitlement - Improved Microcontroller Kit with new support for many 32-bit targets from Arduino, Adafruit and SparkFun
