This question builds on my last one. Consider that I use arrays of X and Y values for two points in order to find the slopes of lines on those points:
formatSpec = 'The slope of a line containing points(%i, %i) and (%i, %i) is %8.4f\n';aX1 = [1, 23];aY1 = [1, 12];aX2 = [2, 8];aY2 = [2, 0];clc;m1 = f_GetSlope(aX1, aY1, aX2, aY2);sprintf(formatSpec, aX1, aY1, aX2, aY2, m1)
I'm now getting the correct slopes. But look what sprintf does with the output:
m1 = 1.0000 0.8000ans =The slope of a line containing points(1, 23) and (1, 12) is 2.0000The slope of a line containing points(8, 2) and (0, 1) is 0.8000
sprintf is not using the first value of each coordinate array and the first value of the answer array for the variables in the format, and then doing the same for the second.
Rather, sprintf just plugs the first and second value of the first input array, the first and second value of the second input array, and the first value of the third input array into the first output line.
Then it takes the second value of the third array, the two values from the fourth array, and the two values from the answer array, and uses those in the second output line.
What a mess! Suggestions?
