I would like to change my array (y) to a table. y is 1a 3 x 133 double. I would also like to name the columns of this table with the names listed. I have checked to see if these names work within matlab with the isvarname function and they work fine. I have also counted these variables and there are 133 . I have also tried this with commas inbetween the variables but I get the same error message. I am not sure why this error message is popping up and any help is much appreciated!
Code:
B = array2table(y, 'VariableNames',{'L_palmPosX' 'L_palmPosY' 'L_palmPosZ' 'L_thumb_basePosX' 'L_thumb_basePosY' 'L_thumb_basePosZ' 'L_thumb_knuckle1PosX' 'L_thumb_knuckle1PosY' 'L_thumb_knuckle1PosZ' 'L_thumb_knuckle2PosX' 'L_thumb_knuckle2PosY' 'L_thumb_knuckle2PosZ' 'L_thumb_tipPosX' 'L_thumb_tipPosY' 'L_thumb_tipPosZ' 'L_index_basePosX' 'L_index_basePosY' 'L_index_basePosZ' 'L_index_knuckle1PosX' 'L_index_knuckle1PosY' 'L_index_knuckle1PosZ' 'L_index_knuckle2PosX' 'L_index_knuckle2PosY' 'L_index_knuckle2PosZ' 'L_index_tipPosX' 'L_index_tipPosY' 'L_index_tipPosZ' 'L_middle_basePosX' 'L_middle_basePosY' 'L_middle_basePosZ' 'L_middle_knuckle1PosX' 'L_middle_knuckle1PosY' 'L_middle_knuckle1PosZ' 'L_middle_knuckle2PosX' 'L_middle_knuckle2PosY' 'L_middle_knuckle2PosZ' 'L_middle_tipPosX' 'L_middle_tipPosY' 'L_middle_tipPosZ' 'L_ring_basePosX' 'L_ring_basePosY' 'L_ring_basePosZ' 'L_ring_knuckle1PosX' 'L_ring_knuckle1PosY' 'L_ring_knuckle1PosZ' 'L_ring_knuckle2PosX' 'L_ring_tipPosX' 'L_ring_tipPosY' 'L_ring_tipPosZ' ' L_pinky_basePosX' 'L_pinky_basePosY' 'L_pinky_basePosZ' 'L_pinky_knuckle1PosX' 'L_pinky_knuckle1PosY' 'L_pinky_knuckle1PosZ' 'L_pinky_knuckle2PosX' 'L_pinky_knuckle2PosY' 'L_pinky_knuckle2PosZ' 'L_pinky_tipPosX' 'L_pinky_tipPosY' 'L_pinky_tipPosZ' 'R_elbowPosX' 'R_elbowPosY' 'R_elbowPosZ' 'R_wristPosX' 'R_wristPosY' 'R_wristPosZ' 'R_palmPosX' 'R_palmPosY' 'R_palmPosZ' 'R_thumb_basePosX' 'R_thumb_basePosY' 'R_thumb_basePosZ' 'R_thumb_knuckle1PosX' 'R_thumb_knuckle1PosY' 'R_thumb_knuckle1PosZ' 'R_thumb_knuckle2PosX' 'R_thumb_knuckle2PosY' 'R_thumb_knuckle2PosZ' 'R_thumb_tipPosX' 'R_thumb_tipPosY' 'R_thumb_tipPosZ' 'R_index_basePosX' 'R_index_basePosY' 'R_index_basePosZ' 'R_index_knuckle1PosX' 'R_index_knuckle1PosY' 'R_index_knuckle1PosZ' 'R_index_knuckle2PosX' 'R_index_knuckle2PosY' 'R_index_knuckle2PosZ' 'R_index_tipPosX' 'R_index_tipPosY' 'R_index_tipPosZ' 'R_middle_basePosX' 'R_middle_basePosY' 'R_middle_basePosZ' 'R_middle_knuckle1PosX' 'R_middle_knuckle1PosY' 'R_middle_knuckle1PosZ' 'R_middle_knuckle2PosX' 'R_middle_knuckle2PosY' 'R_middle_knuckle2PosZ' 'R_middle_tipPosX' 'R_middle_tipPosY' 'R_middle_tipPosZ' 'R_ring_basePosX' 'R_ring_basePosY' 'R_ring_basePosZ' 'R_ring_knuckle1PosX' 'R_ring_knuckle1PosY' 'R_ring_knuckle1PosZ' 'R_ring_knuckle2PosX' 'R_ring_knuckle2PosY' 'R_ring_knuckle2PosZ' 'R_ring_tipPosX' 'R_ring_tipPosY' 'R_ring_tipPosZ' 'R_pinky_basePosX' 'R_pinky_basePosY' 'R_pinky_basePosZ' 'R_pinky_knuckle1PosX' 'R_pinky_knuckle1PosY' 'R_pinky_knuckle1PosZ' 'R_pinky_knuckle2PosX' 'R_pinky_knuckle2PosY' 'R_pinky_knuckle2PosZ' 'R_pinky_tipPosX' 'R_pinky_tipPosY' 'R_pinky_tipPosZ'});
Error:
The VariableNames property must contain one name for each variable in the table.

That looks like it should work.
Try this:
B = array2table(y)
first, to be sure that all the columns in ‘y’ are actually being assigned to columns in ‘B’. I suspect that they aren’t.
