I used sprintf Mt1a to receive a value which someone not experienced with matlab would understand the value ,there appears to be a conflict in " Mt1a+Mt2a " which gives me multiple values ,i tried using str2double to fix my result but it returns NaN ,how can i fix the result for b ?
b=sprintf('%.0f\n',a./str2double(Mt1a+Mt2a)) % ==>how i attempted to use str2double
‘I used sprintf because that's the only command i know of ,to get from Mt1a= 2.152845579898380e+05 toMt1a=215285.’
They are the same. Use the format function to change the way they appear in the workspace.
If you want to eliminate the fractional part of the numbers, use the round, fix, floor or ceil functions, depending on the result you want. (I provided a link to round, links to the others are in that documentation.)

Do you want to concatenate a number and a piece of text together?
a = '1234'; % a is a char vector
b = 5;
c = [a, num2str(b)]
as = "1234"; % as is a scalar string
b = 5;
cs = as + b % automatically converts 5 to "5" then appends it to as
Or do you want to add them?
d = a + b % add 5 to the ASCII values of the characters '1', '2', '3', and '4'
d2 = double('6789')
f = str2double(a)+b % add 5 to the number represented by a
f2 = double(as)+b % double on a string array converts it to the number it represents
