plot(x,y)

Use a colon to create the vectors instead of a semicolon, and be sure the vectors are equal length:

x = 1:5;
y = 5:9;

plot(x,y)

alternatively, if you want to define ‘x’ and ‘y’ as 2-element vectors:

x = [1 5];
y = [6 9];

plot(x,y)

Both will work.

now when i put semicolon nothing is showing up, no figure at all

[Palvasha Turial]

it is the same as before, no line

[Star Strider]

Do not use the semicolon, except to end a statement (when you do not want to see the output) or unless you want to vertically concatenate rows of a matrix or vector.

See MATLAB Operators and Special Characters for more information on them.

even when i dont use it is still the same, no line on the figure

thank you all

Please use a version of the code I provided. Those will work.

The code you are attempting to run will not work and will likely throw errors.

Please see Getting Started or MATLAB Onramp (or preferably both of these) to understand how MATLAB works and how to write useful scripts.
