NAME

matlab88 - manipulate matrices

SYNOPSIS

matlab88

DESCRIPTION

matlab88(1) is a public-domain FORTRAN77 program that allows the user to manipulate small matrices. It dates back to at least 1980. This version is derived from a version ported to the Amiga platform in 1988 from a VAX/VMS platform version.

This program has nowhere near the capabilities of more recent commerical (non-PD) versions of matlab(1); See MATLAB and OCTAVE on the Internet if you need something more powerful.

This code originally dates back to before IF-ELSE-ENDIF and CHARACTER were commonly available and has not been extensively updated. It still makes heavy use of HOLLERITHs and makes some assumptions about the number of characters per word in a few routines but is otherwise portable between platforms and still compilable from f90 and f95 compilers that are friendly enough to support the pre-FORTRAN77 HOLLERITH constructs.

EXAMPLES

// ---------------------------------------------------------------------------- // For this session the <> character is the MATLAB prompt. <> a=<1 2 3;5 4 6;7 8 9> <--- you enter this A = <--- MATLAB response 1. 2. 3. 5. 4. 6. 7. 8. 9. <> b=<5;6;7> <--- you enter this B = <--- MATLAB response 5. 6. 7. <> a*b <--- you enter "multiply a and b" ANS = <--- MATLAB response 38. 91. 146. <> b*a <---you enter "multiply b and a" /--ERROR <--- MATLAB response INCOMPATIBLE FOR MULTIPLICATION <> det(a) <--- Take the determinant of a ANS = <---MATLAB response 18. <> exit <--- you quit MATLAB total flops 34 ADIOS // ----------------------------------------------------------------------------

 INTRO Welcome to MATLAB.

       Here are a few sample statements:

       A = <1 2; 3 4>
       b = <5 6>'
       x = A\b
        = eig(A),  norm(A-V*D/V)
       help \ , help eig
       exec('demo',7)
