Signal plot - Can't figure out error

t1= [0 5];
t2a = [5 6]; 
t2b = [6 7];
t3 = [7 10];
Eo1 = exp(1i*pi);
phi = 2*pi/3; % any angle as its the slope
k = -phi/(t2a(1)-t1(1));
Eo2a =  @(t)exp(1i*(phi + k*(t-t1(1))));
Eo2b = exp(1i*0);
Eo3 = 0;
t= [t1; t2a; t2b; t3];
Eo = [Eo1; Eo2a(t2a); Eo2b; Eo3];
 %% this should be the figure below. 
 plot(t, real(Eo), 'DisplayName','Real')
 plot(t, imag(Eo), 'DisplayName','Im')

What am I doing wrong? -- as I don't get the below plot Eo as outcome

[Walter Roberson]

You define Eo2a as a function handle but you do not use it. You plot Eo but you do not define it.

I did; just updated the code :)

I get the error -> Error in Uin : Dimensions of arrays being concatenated are not consistent.

[Walter Roberson]

Are any of t1, t2a, t2b, t3 non-scalar ?

I suspect that phi should be in radians; it looks like you are using degrees.

[Walter Roberson]

You define k in terms of t2a(1) and t1(1) . That implies you think t1 and t2a are vectors.

You define Eo1 as a scalar constant.

You define Eo2a as a function handle, and pass the vector t2a to it, getting back a vector of results. It might be a row vector rather than a column vector. When you try to use [A;B] between a scalar and a row vector, that is not going to work.

I edited as per your comments - but still no output

t1= [0 5];
t2a = [5 6]; 
t2b = [6 7];
t3 = [7 10];
Eo1 = exp(1i*pi);
phi = 2*pi/3; % any angle as its the slope
k = -phi/(t2a(1)-t1(1));
Eo2a =  @(t)exp(1i*(phi + k*(t-t1(1))));
Eo2b = exp(1i*2*pi);
Eo3 = 0;
t= [t1; t2a; t2b; t3];
Eo = [Eo1; Eo2a; Eo2b; Eo3];
 %% this should be the figure below. 
 plot(t, real(Eo), 'DisplayName','Real')
 plot(t, imag(Eo), 'DisplayName','Im')

It is basically this that would give out the plot shown above-

Eo2a is a function handle...you have to input t and get output. You should run something like below. REthink on your code.

t1= [0 5];
t2a = [5 6];
t2b = [6 7];
t3 = [7 10];
Eo1 = exp(1i*pi);
phi = 2*pi/3; % any angle as its the slope
k = -phi/(t2a(1)-t1(1));
Eo2a =  @(t)exp(1i*(phi + k*(t-t1(1))));
Eo2b = exp(1i*2*pi);
Eo3 = 0;
t= [t1; t2a; t2b; t3];
Eo = [Eo1 Eo2a(t1) Eo2b ];
%% this should be the figure below.
plot(t, real(Eo), 'DisplayName','Real')
plot(t, imag(Eo), 'DisplayName','Im')

Hi, KSSV; thanks for your input - I tried this way too- but I still don't get this output (Eo)

[KSSV]

I have only solved the error.....didn't work on the real problem.
