Basically need help with the syntax, I need to have the first column of the table a string array of characters and the next three a matrix of numerical values

str = 'Hi this is demo:' ; % a string
val = rand(1,3) ;
fprintf('%s %f %f %f\n',str,val)

I tried this format, but matlab evaluates the second character string with %f, say str=["Bob" "Sue" "Jim" "Phil"] matlab returns "Bob NaN NaN NaN NaN" Is there any way to prioritize the first input argument (str) to get matlab to evaluate the whole string before moving on to the numerical array? Sorry if I'm bad at explaining this

str=["Bob" "Sue" "Jim" "Phil"] ;
fprintf([repmat('%s ',1,length(str)),'\n'],str)
