Concatenate signals ( sine wave and a line )

How can I concatenate a sine wave and a line? I tried something and the error was : Dimensions of matrices being concatenated are not consistent.

I assume you tried to vertically(horizontally) concatenate two row(col) vectors of different length.

Could you provide more details?

t = [0:0.1:2*pi]

a = sin(t);

X = [0.1,0.4];

Y = [0.1,0.1];

total=[a; X; Y];

plot(total)

i tried this code

[Timo Dietz]

Not sure what you want to plot. A sine wave with a line at its end?

[Bianca Ivan]

yes

Answer 1

[KALYAN ACHARJYA]

total=[a X Y];

Here "a" is row data, so you must have row-wise (horizontally) concatenate

Answer 2

[Star Strider]

You are attempthing to vertically concatenate them.

Use commas (,) instead fo semicolons(;) and it will work. Commas horizontally concatenate and semicolons vertically concatenate.

See MATLAB Operators and Special Characters for details.

Answer 3

I guess you want to add a X/Y line after the sine wave, right?

In this case you have to concatenate X + t and Y + a in order to have a new total X and total Y vector.

Looks weird but is this what you wanted to have: plot([t X], [a Y])

Thank you! I have to change the vectors values
