simtb_est_accuracy() - Determines the accuracy of the estimated features
Usage:
>> A = simtb_est_accuracy(est, true)
INPUTS:
est = [mobservations x nC] matrix of estimated features (TCs or SMs)
true = [mobservations x nC] matrix of true features
NOTE: Columns of est and true features should correspond, that is,
they should be in the same order.
OUTPUTS:
A = [nC x 1] vector of accuracies (R^2 statistics)
between each estimated and true features
