matlab: how to print string and variable inline

Question

I am new to matlab.

I am used to python. In python i generally do the below to print text and string together

a=10
b=20
print("a :: "+str(a)+" :: b :: "+str(b))

In matlab we have to use sprintf and use formats. But is this python kind of printing possible in matlab with any way.

As of MATLAB R2016b you can write:

disp("a :: "+string(a)+" :: b :: "+string(b)))

You can also use the concatenation operator '[]':

disp (['a :: ' num2str(a) ' :: b :: ' num2str(b)])

The first example uses the string array while the second uses character array.

You don't even need the explicit string(...) conversions. Most types will automatically be converted to strings when you do "some string" + x. So disp("a :: " + a + " :: b :: " + b) would work too.

You can use disp function to print and num2str to convert number to string

disp (['a :: ' num2str(a) ' :: b :: ' num2str(b)]

Using formatted print(fprintf) you can do that:

name = 'Alice';   
age = 12;
fprintf('%s will be %d this year.\n',name,age);

Also you can use disp command.
