Document Summary
Programming: for loops for indexer = expression end. Used to repeat calculations for a specific # of times or iterations. Element by element matrix calculation for loop: plug each value or quantity into voltage vector. Voltage = 1:0. 001:20; for n=1:length(voltage) pressure(n) = 3*voltage(n)^3+5*voltage(n)^-1/voltage(n)^2; end plot(voltage,pressure) if-else (conditional statements) if logical expression. Similar to a for loop, the difference being that you decide the number of iterations. While loops have a higher chance of an infinite loop if code is written incorrectly or if mistakes were present. Spreadsheet has measurement of blood cell size in a sample of blood (cell width) We want to know how many red blood cells, platelets and leukocytes were present in the sample. Need to scan through the spreadsheet, examine each measurement, determine the cell type and report the results. Need to write a matlab code to display the findings. Countunknown; for n=1:length(cells) % scans each measurement value if cells(n)<=6 && cells(n)<=8.
