how to use who to get a list of variable in the workspace and then use them as variables in a function?

>> who

Your variables are:

Angle2G_1_phi90 Angle5G_3_tot_th90 Power2G_5_th90 Angle2G_1_th90 Angle5G_4_phi90 Power2G_5_tot_th90 Angle2G_1_tot_th90 Angle5G_4_th90 Power2G_6_phi90 Angle2G_2_phi90 Angle5G_4_tot_th90 Power2G_6_th90 Angle2G_2_th90 Angle5G_5_phi90 Power2G_6_tot_th90 Angle2G_2_tot_th90 Angle5G_5_th90 Power5G_2_phi90 Angle2G_3_phi90 Angle5G_5_tot_th90 Power5G_2_th90 Angle2G_3_th90 Angle5G_6_phi90 Power5G_2_tot_th90 Angle2G_3_tot_th90 Angle5G_6_th90 Power5G_3_phi90 Angle2G_4_phi90 Angle5G_6_tot_th90 Power5G_3_th90 Angle2G_4_th90 Power2G_1_phi90 Power5G_3_tot_th90 Angle2G_4_tot_th90 Power2G_1_th90 Power5G_4_phi90 Angle2G_5_phi90 Power2G_1_tot_th90 Power5G_4_th90 Angle2G_5_th90 Power2G_2_phi90 Power5G_4_tot_th90 Angle2G_5_tot_th90 Power2G_2_th90 Power5G_5_phi90 Angle2G_6_phi90 Power2G_2_tot_th90 Power5G_5_th90 Angle2G_6_th90 Power2G_3_phi90 Power5G_5_tot_th90 Angle2G_6_tot_th90 Power2G_3_th90 Power5G_6_phi90 Angle5G_2_phi90 Power2G_3_tot_th90 Power5G_6_th90 Angle5G_2_th90 Power2G_4_phi90 Power5G_6_tot_th90 Angle5G_2_tot_th90 Power2G_4_th90 Angle5G_3_phi90 Power2G_4_tot_th90 Angle5G_3_th90 Power2G_5_phi90

these are strings and I want to use them like.

>> a = who

a =
