Math helpers and array operators. See CINT for rounding (nearest, .5 away from zero), INT for floor and FIX for truncation. EVAL evaluates a string as an expression (EVAL). MATH() uses a space after the name, not extra parentheses: MATH(ATAN3 x, y) not MATH(ATAN3(x,y)). TYPE arrays use arr().member the same way as plain a() (PIXEL too; see TYPE). OPTION ANGLE DEGREES applies to ATAN3 and Q_*.
CINT(n) EVAL(expr$) MATH(fn args) MATH command SET|SCALE|ADD|MUL|POWER|INTERPOLATE|SLICE|INSERT|M_*|V_*|Q_*|FFT
n - value for CINT expr$ - expression string for EVAL a(), b(), c() - numeric arrays; TYPE views use pts().x style
Functions: MATH(ATAN3 x, y) angle of vector (x,y) in 0..2*PI MATH(SINH a) MATH(COSH a) MATH(TANH a) MATH(LOG10 a) MATH(MAX a()) MATH(MIN a()) MATH(MEAN a()) MATH(MEDIAN a()) MATH(SUM a()) MATH(SD a()) (SD is sample stdev, n-1) MATH(MAGNITUDE v()) MATH(DOTPRODUCT a(), b()) MATH(M_DETERMINANT a()) MATH(CHI a()) MATH(CHI_P a()) MATH(CORREL a(), b())
Commands: MATH SET n, a() MATH SCALE a(), k, b() or a(), b(), c() MATH SCALE pts().x, k, pts().x MATH ADD a(), k, b() or a(), b(), c() MATH MUL a(), b(), c() element-wise MATH INTERPOLATE a(), b(), t, c() MATH SLICE a(), i, , b() (omit one index) MATH INSERT a(), i, , b() MATH M_INVERSE a(), b() MATH M_TRANSPOSE a(), b() MATH M_MULT a(), b(), c() MATH M_PRINT a() MATH V_PRINT a() MATH V_NORMALISE a(), b() MATH V_MULT m(), v(), o() MATH V_CROSS a(), b(), c() MATH Q_INVERT|Q_VECTOR|Q_EULER|Q_CREATE|Q_MULT|Q_ROTATE MATH FFT a(), b() (also INVERSE|MAGNITUDE|PHASE)
Example:
PRINT CINT(45.57)
PRINT EVAL("1+2*3")
PRINT MATH(SUM A())
