a=[1 2 3 4];
b=num2str(a);
b(b==' ')=[];
out=str2num(b)

There are many ways. One way
a = [1 2 3 4];
b = num2str(b);
b(isspace(b)==1) = [];
a = str2num(b);

Might this work?
a=[1 2 3 4] ;
b='';
for i=1:size(a,2)
b=[b num2str(a(i))];
end
str2double(char(b))

Avoid the overhead of converting numbers into strings and back ... Use simple school math and a matrix multiplication:
a = [2 3 0 1 5]
b = 10.^(numel(a)-1:-1:0) * a(:)
