sfrtoc: Convert real data to complex (by adding zero imaginary part).

sfrtoc < real.rsf > cmplx.rsf

See also: sfcmplx

The input to sfrtoc can be any type=float dataset:

bash$ sfspike n1=10 n2=20 n3=30 >real.rsf
bash$ sfin real.rsf
real.rsf:
    in="/var/tmp/real.rsf@"
    esize=4 type=float form=native 
    n1=10          d1=0.004       o1=0          label1="Time" unit1="s" 
    n2=20          d2=0.1         o2=0          label2="Distance" unit2="km" 
    n3=30          d3=0.1         o3=0          label3="Distance" unit3="km" 
        6000 elements 24000 bytes

The output dataset will have type=complex, and its binary will be twice the size of the input:

bash$ <real.rsf sfrtoc >complex.rsf
bash$ sfin complex.rsf 
complex.rsf:
    in="/var/tmp/complex.rsf@"
    esize=8 type=complex form=native 
    n1=10          d1=0.004       o1=0          label1="Time" unit1="s" 
    n2=20          d2=0.1         o2=0          label2="Distance" unit2="km" 
    n3=30          d3=0.1         o3=0          label3="Distance" unit3="km" 
        6000 elements 48000 bytes
