averf
Average, standard deviation and rms of vector/scalar fields

Description ```AF = averf(F) returns the average of the vector/scalar fields F. AF is a field of the same type as F (i.e., vector or scalar), whose elements are the average of the elements of the fields F. Depending on the nature of the fields, AF corresponds to a time average, an ensemble average, or a phase average. [AF, STD, RMS] = averf(F,..) returns additional scalar fields: - STD, standard deviation: at each location (x,y), one has: STD(u) = < [ u - <u> ]^2 >^(1/2), where <> is a temporal avg. - RMS, root mean square: at each location (x,y), one has: RMS(u) = < u^2 >^(1/2) By default, averf considers that the zero elements of F are erroneous, and does not include them in the computations. If however you want to force the zero elements to be included in the computations, specify averf(F,'0'). If no output argument is specified, the average field AF is displayed. Examples v = loadvec('*.vc7'); showf(averf(v)); [m, std, rms]=averf(vec2scal(v,'uy')); showf(std); averf *.vc7 % shows the average of the files matching *.vc7 See Also smoothf, spaverf, subaverf, azaverf, phaseaverf, statf Published output in the Help browser showdemo averf ```
