    Syntax

    [A1,...,An] = fromRadians(toUnits,R1,...,Rn)

    Description

    [A1,...,An] = fromRadians(toUnits,R1,...,Rn) converts the angles specified by R1,...,Rn from radians to the units specified by toUnits. This function is useful for converting angles from radians when you do not know the output units until run-time.

    Convert several values from radians to degrees.

    [A1,A2,A3,A4] = fromRadians("degrees",pi/2,pi,3*pi/2,2*pi)
    A1 = 
90

    A2 = 
180

    A3 = 
270

    A4 = 
360

    Convert the same values from radians by specifying an array.

    R = [pi/2 pi 3*pi/2 2*pi];
A = fromRadians("degrees",R)
    A = 1×4

    90   180   270   360

    Input Arguments

    Output unit, specified as "degrees" or "radians". You can also specify abbreviations such as "deg" and "rad".

    Data Types: char | string

    Angles in radians, specified as one or more numeric arrays.

    Output Arguments

    collapse all

    Angles in degrees or radians, returned as the same number of numeric arrays as in R1,...,Rn. The size of each output array matches the size of the corresponding input array.
