Mathcad Toolbox Contents:
CurrentDirectory(1)  Gets or sets the fully qualified path of the current working directory. DocumentDirectory(1)  Gets the fully qualified path of the current document. GetFolderPath(1)  Gets the path to the system special folder identified by the specified enumeration. GETWAVINFO(1)  Creates a vector with four elements containing information about file. interp(4)  (vs,vx,vy,x) returns an interpolated value at x from the coefficients in vector vs, and the original data in vx and vy. Play(1)  Play sound file. pspline(2)  (vx,vy) returns a vector of second derivatives to build a cubic spline parabolic at the endpoints. pspline(3)  (vx,vy,x) returns a vector of second derivatives to build a cubic spline parabolic at the endpoints. lspline(2)  (vx,vy) returns a vector of second derivatives to build a cubic spline linear at the endpoints. lspline(3)  (vx,vy,x) returns a vector of second derivatives to build a cubic spline linear at the endpoints. READBIN(6)  ( file, type, endian, cols, skip, maxrows ) returns an array containing the binary data in file. READBMP(1)  Creates an array containing a grayscale representation of a bitmap format image file. READRGB(1)  Creates an array containing a redgreenblue packed matrix representation of the image file. READWAV(1)  Creates a matrix containing signal amplitudes in file. READ_BLUE(1)  Returns a matrix representing the RGB blue component of the image in file. READ_GREEN(1)  Returns a matrix representing the RGB green component of the image in file. READ_IMAGE(1)  Creates an array containing a grayscale representation of the image file. READ_RED(1)  Returns a matrix representing the RGB red component of the image in file. rfile(2)  ( path, filename ) Reads an expression from the file. Rkadapt(3)  (ode,y(x),xmax) uses the RungeKuttaFehlberg method (RKF45). Rkadapt(4)  (ode,y(x),xmax,steps) uses the RungeKuttaFehlberg method (RKF45). Rkadapt(5)  (ics,xmin,xmax,steps,D(x,y)) uses the RungeKuttaFehlberg method (RKF45). rkfixed(3)  (ode,y(x),xmax) uses the fourthorder RungeKutta fixedstep method. rkfixed(4)  (ode,y(x),xmax,steps) uses the fourthorder RungeKutta fixedstep method. rkfixed(5)  (ics,xmin,xmax,steps,D(x,y)) uses the fourthorder RungeKutta fixedstep method. wfile(3)  ( value, path, filename ) Writes the expression to the file. WRITEBIN(4)  ( file, type, endian, M ) writes an array of scalars to the binary data file named file. WRITEWAV(4)  ( file, s, b, M ) Creates a WAV signal file out of a matrix.
