IBMF is the matrix of IBM/360 32-bit floats each               stored as a 32 bit unsigned big-endian integer               in a MATLAB double.               The format of a IBM/360 32-bit float is:                  sign 7-bit exponent  24 bit fraction                  The base is 16. The decimal point is to                  the left of the fraction. The exponent is                  biased by +64.               The basic idea is that you use floating point on               the various fields.               ieee = sign * 16 ^ (exponent - 64) * fraction / 16 ^ 6 By:           Martin Knapp-Cordes               The MathWorks, Inc.
