How to concatenate data from two different functions in MATLAB?

Part of one function has this:

%% Concatenating Time & Point to Point Angles. Time will be the first column
ConcPTP1 = [TimeP2P1,P2PAng1]; %% getting the datat from here works

Part of the other function has this:

%% Concatenating Time & Angles. Time will be the first column
ConcLin1 = [TimeLin1,AnglesLin1]; %% getting the datat from here works too

Part of the main program has this

%% Collecting all Data
Concat = [ConcPTP1',ConcLin1']'; %%% ***my problem is here*** works only if everything is in one script

This works when everything is a single script but gives errors when I seperate the files as functions then call them from a main program. (The function method is needed). Everything else works fine, I only need to combine all the data from both functions as one ouput file.

Thank you in advance.

You need to return the ConcPTP1 and ConcLin1 variables as outputs from your functions. Can you show us the code for these function signatures and how you are currently calling them?

[Walter Roberson]

As James suggests, add ConcLin1 as an output from Line(), and add ConcPTP1 as an output from Point()

@Walter Roberson @James Tursa thank you. Your suggestion helped a great deal.

As you correctly mentioned for Line:

% Before:
% function AnglesLin1 = Line(nx, ny, nz, sx, sy, sz, ax, ay, az,ResLin1,Xstart,Ystart,Zstart,Xend,Yend,Zend)
% correction:
function [AnglesLin1,ConcLin1] = Line(nx, ny, nz, sx, sy, sz, ax, ay, az,ResLin1,Xstart,Ystart,Zstart,Xend,Yend,Zend)

As you correctly mentioned for Point:

% Before:
% function AnglesPTP1 = Point(X, Y, Z, nx, ny, nz, sx, sy, sz, ax, ay, az,iniPTP1,condiPTP1)
% correction:
function [AnglesPTP1,ConcPTP1] = Point(X, Y, Z, nx, ny, nz, sx, sy, sz, ax, ay, az,iniPTP1,condiPTP1)

Also the script for calling Point must be corrected as well :

%% Calling PTP Motion
% Before:
% PTPIKine = Point(X, Y, Z, nx, ny, nz, sx, sy, sz, ax, ay, az,iniPTP1,condiPTP1);
% correction:
[AnglesPTP1,ConcPTP1] = Point(X, Y, Z, nx, ny, nz, sx, sy, sz, ax, ay, az,iniPTP1,condiPTP1);

Script for calling Line:

%% Calling Linear Motion
% Before:
% LineIKine = Line(nx, ny, nz, sx, sy, sz, ax, ay, az, ResLin1,Xstart,Ystart,Zstart,Xend,Yend,Zend);
% correction:
[AnglesLin1,ConcLin1] = Line(nx, ny, nz, sx, sy, sz, ax, ay, az, ResLin1,Xstart,Ystart,Zstart,Xend,Yend,Zend);

[ConcPTP1',ConcLin1']'

Three ctranpose operations seems a bit inefficient: why not just concatenate with the correct orientation in the first place?

I am guessing something like this might wrk:

[ConcPTP1;ConcLin1]

If that is not possible, replace the complex conjugate transpose with transpose.

Thank you @Stephen. Fantastic idea. I tried it and it gives the same output. Much simpler way, indeed.

Hence MATLAB community is important. Cheers!

How to concatenate data from two different functions in MATLAB?

Functions:

1)

% Before:
% function AnglesLin1 = Line(nx, ny, nz, sx, sy, sz, ax, ay, az,ResLin1,Xstart,Ystart,Zstart,Xend,Yend,Zend)
% correction:
function [AnglesLin1,ConcLin1] = Line(nx, ny, nz, sx, sy, sz, ax, ay, az,ResLin1,Xstart,Ystart,Zstart,Xend,Yend,Zend)

2)

% Before:
% function AnglesPTP1 = Point(X, Y, Z, nx, ny, nz, sx, sy, sz, ax, ay, az,iniPTP1,condiPTP1)
% correction:
function [AnglesPTP1,ConcPTP1] = Point(X, Y, Z, nx, ny, nz, sx, sy, sz, ax, ay, az,iniPTP1,condiPTP1)

Script:

%% Calling PTP Motion
% Before:
% PTPIKine = Point(X, Y, Z, nx, ny, nz, sx, sy, sz, ax, ay, az,iniPTP1,condiPTP1);
% correction:
[AnglesPTP1,ConcPTP1] = Point(X, Y, Z, nx, ny, nz, sx, sy, sz, ax, ay, az,iniPTP1,condiPTP1);

%% Calling Linear Motion
% Before:
% LineIKine = Line(nx, ny, nz, sx, sy, sz, ax, ay, az, ResLin1,Xstart,Ystart,Zstart,Xend,Yend,Zend);
% correction:
[AnglesLin1,ConcLin1] = Line(nx, ny, nz, sx, sy, sz, ax, ay, az, ResLin1,Xstart,Ystart,Zstart,Xend,Yend,Zend);

Now, using the line of code below works to concatenate the needed values:

%% Collecting all Data
% Before:
Concat = [ConcPTP1',ConcLin1']';
% A Simpler way is:
Concat = [ConcPTP1;ConcLin1];
