Build 06 Specific Changes

Below is a list of changes and improvements specific to DADiSP 6.5 B06:

New Features and Functions

Larger Address Space

B06 is built to be aware of the larger address space provided by 64-bit Windows. Although still a 32-bit program, DADiSP 6.5 B06 now has full access to the 4GB address space provided by 64-bit Windows. On 64-bit systems with a large amount of on-board RAM, B06 will generally run faster with big data by operating directly in RAM and avoiding memory page swaps.

New ProPac Math Accelerator Module

The new DADiSP/ProPac Module combines the VectorXL module with the FFTXL and MatrixXL modules to provide a single, optimized numeric processing engine. Together, all three modules deliver accelerated vector math, FFT and matrix computations by using the Math Kernel Library from Intel. Speed improvements of 20% up to a factor of 50x are common.

Data Processing

1. BLOCKMAX computes the non-overlapping block maximum of a series.
2. BLOCKMEDIAN computes the non-overlapping block median of a series.
3. BLOCKMIN computes the non-overlapping block minimum of a series.
4. MOVMEDIAN computes the N-point moving median of a series.
5. REPCOLUMN replicates the columns of a series.
6. REPELEMENTS replicates individual elements of a series.
7. SEREXTRACT extracts multiple sections from a series.

Signal Processing

1. DEMODAM demodulates an amplitude modulated series.
2. MEDFILT1 performs median filtering of a series.

Cursor Functions

1. CURLOCSET sets cursor X locations of one or more windows based on a source window.
2. CUREXTRACT extracts one or more series from a source window based on cursor indices.
3. CURPOSSET sets cursor index positions of one or more windows based on a source window.
4. CURXEXTRACT extracts one or more series from a source window based on cursor X locations.

Special Functions

1. BETAINCINV computes the inverse regularized incomplete beta function.
2. COSINT computes the cosine integral.
3. DAWSON computes the Dawson integral.
4. EXPINTEI computes the Cauchy principal value exponential integral.

6. ERFI computes the imaginary error function.
7. FACTORIAL computes the factorial for positive integers.
8. FADDEEVA computes the Faddeeva function.
9. GAMMAINCINV computes the inverse regularized incomplete gamma function.
10. HANKEL generates a Hankel matrix.
11. SININT computes the sine integral.
12. TOEPLITZ generates a Toeplitz matrix.
13. VANDER generates a Vandermonde matrix.

Colors

1. COLORTORGB converts a color index into RGB values.
2. RGBTOCOLOR converts RGB values into a color index.
3. SETCOLORBARLABEL sets the label for a COLORBAR.

Misc

1. New |^ operator performs bitwise exclusive or.
2. The __FILE__, __FUNC__ and __LINE__ macros return the filename, function name and line number of the current SPL routine.

Improvements and Changes

1. LARGEADDRESS mode supports more program memory on 64 bit Windows.
2. Faster and more accurate implementation of ERF, ERFC and ERFCX by using the complex FADDEEVA function.
3. GAMMA and GAMMALN use fast Lanczos approximation for speed and accuracy.
4. MOVMAX and MOVMIN handle complex series.
5. Date/time axes supported for XYZ and surface plots.
6. PRESERVE_WINDOW_LABELS configuration parameter supports "sticky" window labels.
7. DEFAULT_LAYOUT configuration parameter supports startup window layout.
8. TIC_X_STYLE and TIC_Y_STYLE configuration parameters determine if a plot is automatically scaled on X/Y tic marks or data range.
9. LOCALE_FORMAT_NUMERIC configuration parameter supports adding thousands separator for numeric display, e.g. 10000 displays as 10,000.
10. Modeless Function Wizard for easier point and click function selection.
11. X data with NaN values plot as gaps.
12. Y data with NaN values plot as gaps for XYZ and surface plots.
13. Faster loading of Worksheets with big data.
