Print from the structure:
To print from the structure, a disp function will show either the whole structure or a field.
>> disp(package)
item_no: 123
cost: 19.9900
price: 39.9500
code: 'g'
>> disp(package.cost)
19.9900
Though, using fprintf, only the individual fields can be printed; the whole structure cannot be printed.
>> fprintf('%d %c\n', package.item_no, package.code)
123 g
Forward substitution: The Forward substitution (done methodically by first getting a 0 in the a 21 place, and then a 31 , and lastly a 32 ): For the Gauss technique,
str2num function - String: The function str2num does the opposite; it takes the string in which a number is stored and converts it to the type double: >> num = str2num('123.
