The quality control data from the titanium bar forging run was stored in the MATLAB workspace file barData.mat. The data is stored in a 2D array named tiBarData: the first column contains the bar lengths in mm, the second column contains the bar widths in mm, the third column contains the bar heights in mm, and the fourth column contains the bar weights in g. The MATLAB statement load('barData.mat','tiBarData'); will load the variable named tiBarDatafrom the barData.mat file into the MATLAB workspace. Make sure the barData.mat file is in the same folder as your program. Bars have a nominal length of 10 mm, a nominal width of 4 mm, and a nominal height of 2mm. Bars that meet the manufacturing standards for sale should meet all of the following criteria: Length within 0.5% (include) of the nominal length. (i.e, the difference between your bar and the nominal bar should be within 0.5% of the nominal length in both directions) Width within 0.5% of the nominal width. Height within 0.25% of the nominal height. Weight should not exceed 362 g. Where do you find the data ?Is the data already on matlab?
