How to solve Vertcat error to PID graph?

I'm trying to run the following code but it sends an error, specifically:

Error using vertcat dimensions of matrices being concatenated are not consistent.

Error in Optimized_response (line 6)

T1 = TF ([25.2 * KD 21.2 * kd + 25.2 * KP 25.2 * ki + 21.2 * KP + 3 * kd 21.2 * ki + 3 * KP

Someone could help me fix it.

The code is:

clc

close all

kd=input('enter the value of kd');

kp=input('enter the value of kp');

ki=input('enter the value of ki');

T1=tf([25.2*kd 21.2*kd+25.2*kp 25.2*ki+21.2*kp+3*kd 21.2*ki+3*kp

3*ki],[1 16.58 25.41+25.2*kd 17.18+21.2*kd+25.2*kp 11.70+25.2*ki+21.2*kp+3*kd 21.2*ki+3*kp+1 3*ki]);

Hi,

try:

kd=input('enter the value of kd');
kp=input('enter the value of kp');
ki=input('enter the value of ki');
T1=tf([25.2*kd 21.2*kd+25.2*kp 25.2*ki+21.2*kp+3*kd 21.2*ki+3*kp+3*ki],...
    [1 16.58 25.41+25.2*kd 17.18+21.2*kd+25.2*kp 11.70+25.2*ki+21.2*kp+3*kd 21.2*ki+3*kp+1 3*ki]);
