In this example let us assume input in the form of a multi-dimensional matrix with three rows ad four columns. Example 2(a) will show output till 2 digits and example 2(b) will show up to four digits. We can observe the difference in both parts 2 (a) and 2 (b) in the form of digits. input data is a multi-dimensional matrix with three rows and three columns for both the examples example 2(a) and example 2(b). In first part, precision is 2 and in second part precision is 4. In this example, num2str function is applied along with precision. And in third part 1 ( c ) input is in form of a multi-dimensional matrix with three rows and three columns so that output will also be in form of a multi-dimensional matrix with three rows and three columns. In the second part, 1 ( b ) input is in the form of an array or we can say vector so the output will also be in the form of an array. The output of all inputs is op1, op2, op3, op4, and op5. In this example 1 ( a ) let us assume five different inputs in1, in2, in3, in4, and in5.all the inputs are integers 4, 7, 12, 55, and 34 respectively. And if we are using num2str function along with format specifier then the output will change as per format given by the user. if precision is 3 then the output will be up to three digits 3.45. Let us assume one number 3.456 if we apply num 2 str function with precision 2 then it will ignore all other digits except the first two digits that means the output will be 3.4. If we are using num2str function with precision then the output will show maximum digits depending on precision. This function converts input data independently if we are using simple function num2str. Output variable name = num2str (input variable name, format of output ) Examples of num2str Matlab

Output variable name = num2str (input variable name, precision value)

Output variable name = num2str ( input variable name ) Hadoop, Data Science, Statistics & others

Matlab change variable name
