I have several different cells. How can I combine them?

I have tried it this way.

a = {'ball' , 'cake' , 'ice'};
b = {'home'};
c = {'car','moto'};
d = {'money'};
e = cell(4,3);
e(1,:) = a;
e(2,1) = b;
e(3,1:2) = c;
e(4,1) = d;

but I would like to know if it can be done in a more general way because I don't know initially the size of each cell a, b, c.

Something like this:

a = {'ball' , 'cake' , 'ice'};
b = {'home'};
c = {'car','moto'};
d = {'money'};
e = cell(4,3);
e(1,1:end) = a;
e(2,1:end) = b;
e(3,1:end) = c;
e(4,1:end) = d;

a = {'ball' , 'cake' , 'ice'};
b = {'home'};
c = {'car','moto'};
d = {'money'};
e = cell(4,0);
e(1,1:numel(a)) = a;
e(2,1:numel(b)) = b;
e(3,1:numel(c)) = c;
e(4,1:numel(d)) = d
e = 4×3 cell array
    {'ball' }    {'cake'    }    {'ice'     }
    {'home' }    {0×0 double}    {0×0 double}
    {'car'  }    {'moto'    }    {0×0 double}
    {'money'}    {0×0 double}    {0×0 double}

"I would like to know if it can be done in a more general way..."

That will not be easy, because you split the data up into lots of separate variables. An efficient more general approach requires them to be kept together.
