Convolute ramp signal and step signal

I am supposed to convolute a unit ramp signal and a step signal (till t =10 secs) and I am getting an error while running my code

x = 1:1:10 ;
p = 0.1:0.1:1 ;

u = ones(1 , 10);
r = p.*u;
y = conv(r,u);

plot(x,y);

Error using plot
Vectors must be the same length.

But all the arrays are of the same length i,e 10

x = 1:1:10 ;
p = linspace(0.1,1,length(x));
u = ones(1 , length(x));
r = p.*u;
y = conv(r,u,'same');
plot(x,y);

Try using additional arguments for conv function

Thanks for the answer VBBV! can you explain what 'same' means here? Matlab help isn't elaborate enough

[Aditya Goel]

w = conv(u,v,shape) returns a subsection of the convolution, as specified by shape. For example, conv(u,v,'same') returns only the central part of the convolution, the same size as u.
