Can someone help me set up MATLAB linear program?? Problem is below

Veronica the owner of Very Veggie Vegeria is creating a new healthy salad that is low in calories but meets certain nutritional requirements. A salad is any combination of the following ingredients: Tomato, Lettuce, Spinach, Carrot, Smoked Tofu, Sunflower Seeds, Chickpeas, Oil.

Each salad must contain: At least 15 grams of protein At least 2 and at most 8 grams of fat At least 4 grams of carbohydrates At most 200 milligrams of sodium At least 40% leafy greens (lettuce and spinach) by mass. Determine the combination of ingredients that minimizes calories but meets all nutritional requirements. i. Formulate the problem as a linear program with an objective function and all constraints. ii. Determine the optimal solution for the linear program using any software you want. Include a copy of the code/file in the report. iii. What is the cost of the low calorie salad?

My objective function is Minimize c1*21 + c2*16 + c3*40 + c4*41 + c5*585 + c6*120 + c7*164 + c8*884 Constraints are Nutritional Constraints (what each salad must have):

Protein: c1*0.85 + c2*1.62 + c3*2.86 + c4*0.93 + c5*23.4 + c6*16 + c7*9 + c8*0 >= 15

Fat: c1*0.33 + c2*0.20 + c3*0.39 + c4*0.24 + c5*48.7 + c6*5 + c7*2.6 + c8*100 >= 2

Fat: c1*0.33 + c2*0.20 + c3*0.39 + c4*0.24 + c5*48.7 + c6*5 + c7*2.6 + c8*100

Carbs: c1*4.64 + c2*2.37 + c3*3.63 + c4*9.58 + c5*15 + c6*3 + c7*27 + c8*0 >= 4

Sodium: c1*.009 + c2*.028 + c3*.065 + c4*.069 + c5*.0038 + c6*.120 + c7*.078 + c8*0

Leafy greens: 0.4a - 0.6b - 0.6c - 0.6d + 0.4e + 0.4f + 0.4 g + 0.4h

ci >= 0 Not sure if my constraints are correct, do I need to negate them or something??

this is as far as I got for setting up Matlab
