MATLAB: How to find number with Matlab

for statementif statementsix digit number

One of my professors has assigned me the task of writing a program to solve a given question:

Find a six digit number in which the first digit is one more than the third, the second digit is one less than the fourth, the fifth digit is one less than the third, and the sixth digit is one more than the fourth. The sum of the second and third digits equals the first. The sum of all digits is thirty

We are only allowed to use nested for and if statements. I have had zero instruction in Matlab and no programming background. I've been trying to figure this out for hours and am completely lost. Could someone please help me out?

That seems to me to be a bit of a strenuous start to a MATLAB course!

If you can do the algebra, then all you need to know is how to code it. Consider the first condition, ‘the first digit is one more than the third’. That becomes d1=d3+1. You have to put all the digit coefficients on the left hand side, and all the constants on the right, so you would code this as d1-d3=1:

D(1,:) = [1 0 -1 0 0 0]     % First Row Of ‘D’ Matrix
K(1,:) = [1]                % First Row Of ‘Constant’ Matrix

The others work the same way. The last row of ‘D’ would be [1 1 1 1 1 1] and the corresponding ‘K’ would be 30. Then if you define ‘N’ as [d1; d2; d3; d4; d5; d6] you have to solve D*N=K for ‘N’. I leave that to you.

I would use the pdist function, and define your own distance metric if it is not one of those already provided.
